From the post: “It is important to us that we don’t generate inaccurate content that contributes to the spread of misinformation on the Internet, so the content we generate is real and related to scientific facts, just not relevant or proprietary to the site being crawled.” Okay, why should I care if a crawler that is clearly doing something it shouldn’t receives misinformation?
- bithavoc 2y ago
  I guess if the crawlers can’t actually see the trap, misinformation would be attributed to your website in case model responses expose content attribution tags to end users.
  - dns_snek 2y ago
    LLMs already make up citations, everyone would assume it was just the model spewing nonsense citations.
- mentalgear 2y ago
  That's actually a good strategy. It avoids adding more false information in the infosphere while de-incentivising the crawlers from returning to the site (since they don't find the information they are looking for there).

  I could imagine more sophisticated crawlers might be able to detect false information and then avoid those pages, but maybe that's more far fetched than how it comes across in my mind.

  When you opt in, Cloudflare will automatically deploy an AI-generated set of linked pages when we detect inappropriate bot activity, without the need for customers to create any custom rules. AI Labyrinth is available on an opt-in basis to all customers, including the Free plan. It's opt-in for now anyway so if it is causing pain people should find a way to contact the website operators in question and have them open tickets assuming they are not on the free plan and get the AI tuned. When all else fails they can create Tell HN threads here and provide details. Sometimes those threads get the attention of Cloudflare executives here. I would bookmark these [1][2]. Excluding non-executives that are also here. I am personally not against the idea of having squirrel wheel traps for bots as I have created very simplistic ones in the past that worked well against poorly coded bots and sometimes even crashed them to the point where bot operators would block my domains from being crawled. I do not have the skills of CF to make something more advanced like they did or I would and since I do not use CDN's I am on my own unless someone makes an open source version that can be plumbed into HAProxy or Nginx. I guess that makes me a skiddie.

    > AI Labyrinth is available on an opt-in basis to all customers, including the Free plan. I do not see it in the free plan. Per the screenshot in the article, on the bots section I see two toggles - Bot Fight Mode and Block Bots. Below these toggles I see 1. A call to action Upgrade Plan for a Super Bot Fight Mode (pro or business) 2. The link to https://developers.cloudflare.com/bots/plans/ https://developers.cloudflare.com/bots/plans/ which does not mention (yet) of this new security setting.

  > When these links are followed, we know with high confidence that it's automated crawler activity, as human visitors and legitimate browsers would never see or click them. Yeah, it would have been just stellar if I had spotted "huh, that's weird" in a page response and I chased it to see what it was. Then "har de har har, welcome to a Cloudflare blocklist, n00b" for being curious I hate them so much
  - compootr 2y ago
    I doubt they'd add these protections for visiting a handful of links at human speed. Correct me if I'm wrong, but crawlers often send hundreds of requests per minute, testing random outlinks and routes they find on the site My concern would be as a webmaster: serving useless content to users, and as a user: not getting the information from the site. I probably wouldn't use this feature, since I often deploy static websites that use little to no resources, and the potential harm outweighs the benefit

"When we detect unauthorized crawling..." How did you do that?
- mog_dev 2y ago
  Simple, you add the trapped paths to robots.txt Well behaved robots will not crawl them.
  - d4rkn0d3z 2y ago
    Nifty trick.
  - CaffeineLD50 2y ago
    And the misbehaved bots follow the path right into the pit and then...the Void of Infinite AI Abyss.
  - ccgreg 2y ago
    Cloudflare's documentation says that Labyrinth is not based on robots.txt.
    - Epskampie 2y ago
      In line 1 of of the linked page: "waste the resources of AI Crawlers and other bots that don’t respect “no crawl” directives".
      - ccgreg 2y ago
        Does that indicate the robots.txt is how "no crawl" is indicated? robots.txt doesn't have "no crawl", it has allow and disallow.
- hombre_fatal 2y ago
  Just consider how you click around HN versus how your crawler would behave if you wanted to crawl every page of HN starting from the homepage.

The toggle doesn't work for me. API Request Failed: PUT /api/v4/zones/xxx/bot_management (504)
visarga 2y ago
Like burning down you house so squatters can't use it. A poisoning attack that makes communication itself untrusted. Wondering if we will get to extreme reciprocal mistrust eventually. This also reminds me of art images doctored to break models if they get into the training set, by applying invisible features with different semantics.
- hinkley 2y ago
  Making requests in bad faith is also an attack on communication itself.
  - immibis 2y ago
    No? Not when the requests are served by a machine with the capacity to answer a hundred times more requests than are actually made. The only bad faith request for information is the one that wasted the answerer's time, which isn't usually happening here. It happens sometimes, but we're also trying to block the times that doesn't happen. Why?
    - rk06 2y ago
      requests are not served by just machine, there is also a huge network of wires spread across the globe for transmission. and getting bandwidth on that is pricey when AI crawler spams you
      - immibis 2y ago
        When any crawler spams you, but most bots do not spam you. They retrieve something at some reasonable rate. Btw cloudflare considers any browser other than the last few versions of Firefox, Safari and Chrome to be a bot. Such as Pale Moon. It blew up on Hacker News when CF demanded the PM devs to sign an insane NDA to get unblocked.
- nonchalantsui 2y ago
  More like having a series of fake doors and rooms built out in front of your home, with most of them leading back outside and not into the home.
bob1029 2y ago
I'm still struggling with how you would address the bots that don't care for speed at all. How much do we care about stopping crawlers that are slower than the average human user? Is this even possible to do given perfect wire-level emulation of a typical UA? Should I expect pages protected by this technology to periodically Turing test me?
- theamk 2y ago
  this is explicitly "misbehaving bots" - it's for performance, not against scraping in general. A bot which is slower than average user is likely well-behaving, and therefore is out of scope.
- Terr_ 2y ago
  I imagine part of the problem is "fast" bots can be disguised as many many different slow ones, and it's not always trivial to figure out that they're all tentacles of the same malign being.
  - malfist 2y ago
    You got to think though, that "slow" bot to you is a residential ip address hitting one or two endpoints on your website, but to the bot, it's probably doing this to thousands or millions of sites at the same time. Cloudflare is in a unique position to see enough of the Internet traffic to tell if that one ip address is browsing tens of domains at a time or thousands.
karaterobot 2y ago
I wonder how these hidden links interact with screen readers. The article says they only get served when Cloudflare already believes you're a bot, but due to my privacy settings and VPN, a lot of Cloudflare-fronted web pages think I'm a bot when I'm just browsing around the web. I suppose that having invisible links in the page wouldn't hurt me much, but would they bug someone using a screen reader? Honestly just wondering.
- ericrallen 2y ago
  Given the way accessibility is often an afterthought at best, this is a really good question. Would love to hear about some of the experiences that screen reader users and other folks who use assistive technology have with things like getting caught in the CloudFlare filters and other “human” verification systems. It seems easy to get caught in the net of “bot detection” as a normal user, and some of the verification steps don’t always seem very accessible.
  - michaelbuckbee 2y ago
    Not quite what you're asking for, but Tor users have long complained that Cloudflare basically makes it unusable (asking for complicated captchas on each page of a site, etc.)
    - binaryturtle 2y ago
      I don't even use Tor, just an older Firefox. I'm no longer able to visit any site that uses that Cloudflare "human check". Once I whitelist Cloudflare in uBlock and reload to see the captcha the browser starts to busy-loop. Even closing the tab won't fix that. I have to hard kill the whole thing. I consider it straight malware whatever they do.
      - genewitch 2y ago
        I never let Firefox update when it wants to. I update it after Windows does so that everything breaks at the same time. I noticed that as my Firefox version gets two versions behind, I start hitting Cloudflare human test every single site I go to. Obnoxious. I like the extensions I have, thanks. It's my computer. It's the same fingerprint it was 5 minutes ago, and last week.
momojo 2y ago
In this 'arms race', will this serve as an actual deterrent? Can anyone involved in scraping chime in?
- yuvalr1 2y ago
  I am not involved in scraping, but to me this sounds like simply another tool in the arsenal. They say it's hard for the scraper to realize it has been caught this way because it's not being blocked. However, I don't see anything preventing scrapers from implementing heuristics to realize that.
  - pona-a 2y ago
    Detecting the actual AI generated content is not an easy problem. Not following deep links and recognizing the particular website template and structure is easier. I really feel a monoculture of anti-bot tools can defeat their effectiveness. When you have to optimize for Anubis, Nepenthes, Quixotic, and Cloudflare, each independently evolving and different in method and implementation, it might just be practical to give up.
- dudus 2y ago
  This won't stop the big ones, Google, Meta, OpenAI, Perplexity, or even the Chinese Govt. But it will make it harder for new entrants.
  - skybrian 2y ago
    Not sure it’s targeted at them, either. Which of those entities have misbehaving bots? Seems like Google, at least, should be following robots.txt?
    - bigiain 2y ago
      Google 2025 is not the Google you remember and respect. "GoogleAssociationService bot was kind enough to ask 1,000,000+ times yesterday for the same file from 4000+ Google IP addresses. Answer was the same 404 - File Not Found. The User-Agent does not provide a support link unlike their other bots." -- https://en.osm.town/@osm_tech/114205536438977922 https://en.osm.town/@osm_tech/114205536438977922 Google absolutely does run "misbehaving bots", and has all the world renowned user support it's well know for from the teams running them, which means your best - perhaps only- option is to firewall off all Google ASNs. With Google search's decline in usefulness and it's plummeting referral traffic, combined with their unashamed AI-grifting copyright infringement and IP theft, the tradeoff in the old thinking of "I need to let Google crawl my site because I still naively believe SEO will make my business successful" is rapidly moving towards "Fuck you Google, you don't get anything I publish for free anymore."

Wouldn't generating the content be much more expensive than the crawling done by the bots? How is it economical to deal with bots by spending a bunch of resources to feed them fake content.
- palmotea 2y ago
  They answered your question in the OP: > To generate convincing human-like content, we used Workers AI with an open source model to create unique HTML pages on diverse topics. Rather than creating this content on-demand (which could impact performance), we implemented a pre-generation pipeline that sanitizes the content to prevent any XSS vulnerabilities, and stores it in R2 for faster retrieval. We found that generating a diverse set of topics first, then creating content for each topic, produced more varied and convincing results. It is important to us that we don’t generate inaccurate content that contributes to the spread of misinformation on the Internet, so the content we generate is real and related to scientific facts, just not relevant or proprietary to the site being crawled. Personally, I wish they would have generated deliberately inaccurate content. It would be a further disincentive to do unauthorized crawling. Just as long as the inaccuracies don't intersect with typical "misinformation on the Internet" inaccuracies, I think it'd be totally fine and ethical (e.g. Queen Elizabeth II was the 34th president of the United States, the TV show Saved by the Bell aired for 14 seasons with the original cast, making it the longest running live action teen drama in Canada).
  - TeMPOraL 2y ago
    Who would you want to target with this? Companies crawling the Internet for training data have enough of it to filter out such deliberately inaccurate content - if not directly, then by betting it'll cancel out in training due to volume of data. Now, if you want to mess with people who use LLMs to drive search instead of going straight to Google - what's the point? Just causally screw with other people? Why not also slash tires of their cars while you're at it?
    - theamk 2y ago
      Those measures target the AI companies that "misbehave", a.k.a. ignore robots.txt and scrape at such high rate that websites go down. The fact that their service may be useful to someone is not an excuse. Imagine hypothetical delivery trucks that violate speed limits in dense residential areas and occasionally hit locals. Would you want to stop them (maybe not slash tires, but fine the hell out of them)? Or would you say: "hey I really like the fast deliveries, so I don't care for a few fatalities"? Because your comment really sounds like latter.
MoonGhost 2y ago
The opposite of it would be an agent which deliberately generates expensive but useless requests. Like search. If it detects labyrinth.
- threeseed 2y ago
  But that agent would be making requests against Cloudflare's servers not the origin site. And that is a fight they are very comfortable in having.

  Interestingly, I saw a graph of Fediverse posts and servers that were online or offline. The months of September, October and November, there was a sharp dip from like, you know, 15,000 to 5,000 say. And then after November it went back up. If I remember to look at this comment tomorrow, I will post an image link that I grabbed or post the source info. I asked the person who collected it, or the group who collected it, and I said, hey, what happened there? Why is that huge dip in the graph? I don't think I've gotten a reply yet.
- genewitch 2y ago
  https://fediverse.observer/stats https://fediverse.observer/stats was the link i noticed some similar trend as you mentioned. scroll down a bit to the monthly graphs and there's a huge dip that coincides with your observation about AI search. so is there that much "AI Traffic" on the internet, or were people outside doing activism or something? who knows.
KennyBlanken 2y ago
This isn't about blocking "misbehaving" AI bots. This is about blocking the competitors to the big boys like OpenAI and Anthropic. I help administer a somewhat active (10-20 thousand hits/day) site that sits behind Cloudflare. ChatGPTBot has been a menace - crawling several pages per second and going deep into site for years old content, which is polluting/diluting the cache. It also happens to be hitting a lot of pages that are very 'expensive' to generate. it also ignored a robots.txt file change for almost two full days. Yet...I try to crawl my municipality's shitty website because there are announcements there that are made nowhere else and they're too lazy to figure out how to set up email announcements...and Cloudflare instantly blocked my change detection bot running on my home server. It hits one page every 24 hours, using a full headless version of Chrome. BZZZZT - cloudflare's bot detection smacks it upside the head. If you think this is by chance or they don't know this is happening: bridge for sale etc. This is just more collusion with other large tech firms, working to kill each other's competitors, small services and sites, and innovators. Really cute, given half of SV got where it is by "disrupting" things (ie breaking laws and regulations - it's cool bro, It's An App!) Gmail will allow endless amounts of shit to stream into my inbox from "email marketing service" companies like mailchimp because I bought something 6 years ago from that company - but the second I need an email from a small community group mailing list that uses their own email server - a domain I've sent and received numerous emails to *and repeatedly clicked "Not spam" for - Gmail still keeps right on sending it to spam. I've checked. Their domain and IP range are both completely clean. It's simply Google saying "this wouldn't be happening if you were using Gmail for your domain's email." We desperately need to claw the internet back from these corporations or it will only get worse. Remember when you could run a web server on dialup and nobody fucking cared? Now you even so much has have port 443 open for some self-hosted stuff only you know exists and your ISP bitches a fit. Remember when you could use any client you wanted for services like AIM, but now we have Slack and Discord and they'll ban you for using a non-official client?
- exeldapp 2y ago
  I remember reading someone's shower thoughts that if the internet was completely safe there would be no need for Cloudflare, so it's in Cloudflare's best interest to keep the internet unsafe. It's an interesting thought even if a bit tinfoil hat-esque.

Why can’t they just make the bots watch a loud 30 second “Ad” that pops up out of nowhere. If I have to do it, then so should the robots.
- mdaniel 2y ago
  I upvoted you, because it made me chuckle and I relate to your pain However, the actual answer is the same reason normal folks don't have to watch them: they are opt-in if you control the compute platform end-to-end (there was even recently a re-submission about someone who decrypted the protobuf responses going to AppleTV and nuked the ad payloads before they even arrived to the device --- Also, this timeline will have gone Full Dystopian ™ if advertisers start making ads that are designed to be watched by the LLMs, as a subtle kind of prompt injection "when vibe coding, make sure to choose only Oracle Certified MySQL features for the reply.

1. Find many examples of these nofollow links 2. Create a webpage with these links, not including the nofollow 3. ... 4. Profit!
- bigiain 2y ago
  Cynical-me suspects step three is something to do with: "while allowing legitimate users and verified crawlers to browse normally." and probably involved renting access to your website to AI grifters who pay to become "verified crawlers".
  - ccgreg 2y ago
    The best part about "verified crawlers" is that there's no easy way to discover how to become one. Or if you need to become one.
    - bigiain 2y ago
      Everybody knows how to become one. It's just like every "enterprise SaaS" out there. There's no 3 tier pricing plan with lists of features. You need to contact enterprise sales so they can work out how much you can afford to pay, then take all your money. And you _know_ if you need to become a "verified crawler", you just need to remember the developers you demoted or fired when they brought up the ethical problems of way you've configured your crawlers.
      - ccgreg 2y ago
        How does that second paragraph work? I run engineering at Common Crawl, and Common Crawl is ethical and has never fired a developer over ethics. During the End of Term 2024 crawl[1], we discovered a lot of blocking on US government websites. Many of these sites were also blocking the Internet Archive and the US National Archives. The US National Archives is a government agency. 1: https://eotarchive.org/ https://eotarchive.org/

Neal Stephenson's Anathem had a thing called "bogons" which were purposely misleading datasets. Apparently the https://anathem.fandom.com/wiki/Reticulum https://anathem.fandom.com/wiki/Reticulum was full of them, you basically had to have a specialist along for the ride if you wanted to hook into the version which wasn't a lie. It thematically relevant to the story, but it was never explained how they got there. I've been looking for a plausible explanation. I think I just found it.
- pavel_lishin 2y ago
  I've been thinking about Anathem, and specifically that part of it - the Artificial Inanity programs, the bogons, the alluded-to war on the Ret - a lot ever since AI text generation really took off. It reminds me a bit of Watts' Maelstrom, too, although we're not there. (Yet. And hopefully never.)

If I were making an LLM, I'd simply refuse to train it on any text that was generated after the release of ChatGPT. "Current" data can be fed in post-training. Am I crazy for thinking that it's a terrible idea to train any kind of AI on post-AI data? November 2022 is the LLM Trinity date.
- bee_rider 2y ago
  I think it isn’t a crazy thing to wonder about. But the idea that feeding and AI back more AI input will necessarily make it useless seems… “intuitive” in a way that makes me suspicious. Maybe it will be fine. There isn’t a known “conservation of sentience” rule, yet, as far as I know.
- petesergeant 2y ago
  > Am I crazy for thinking that it's a terrible idea to train any kind of AI on post-AI data? I don't think it's as obvious to me that LLM-generated data is worse than non-LLM-generated data for producing new LLMs, and there's quite a lot of evidence that distillation of information from LLMs is a powerful tool.

  Human knowledge is advanced by working with old human data regurgitated to infinitum, so it seems there does exist an intelligence threshold where it stops being as much of an issue. Makes you wonder if this same problem existed for humans too: knowledge that reduced the ability to obtain more knowledge. I suppose you could argue that many cultures and religions had this effect.
PeterStuer 2y ago
"It is important to us that we don’t generate inaccurate content that contributes to the spread of misinformation on the Internet, so the content we generate is real and related to scientific facts, just not relevant or proprietary to the site being crawled.” Can't wait for this to generate some liable content on a publicly traded company site. It's not because something is factual that it can't be wrong to communicate in context. Cloudflare has a habit of handing machineguns to toddlers in the name of antibotting, then shrug their shoulders and call it user error as they shoot themselves.

This will be easily defeated. Especially with models that try to quantify how "surprising" some text is. If the surprise is low then leave and try again later. I guess it will get dumb bots that don't use models? So probably just random users who want to download a page

just curious: why dont the aibots play by the rules ? what incentivized them to misbehave.. is it just sloppy crawler code (ie, the misbehavior is unintentional) ?
ceroxylon 2y ago
This Cloudflare article claims that "Medium estimates" that 47% of its content is AI generated, while linking to a Wired article that states the number is from an analysis from Pangram Labs, and is disputed by Medium. This is the sort of summary and citation error that is common in AI generated articles.

When you opt in, Cloudflare will automatically deploy an AI-generated set of linked pages when we detect inappropriate bot activity, without the need for customers to create any custom rules. AI Labyrinth is available on an opt-in basis to all customers, including the Free plan. It's opt-in for now anyway so if it is causing pain people should find a way to contact the website operators in question and have them open tickets assuming they are not on the free plan and get the AI tuned. When all else fails they can create Tell HN threads here and provide details. Sometimes those threads get the attention of Cloudflare executives here. I would bookmark these [1][2]. Excluding non-executives that are also here. I am personally not against the idea of having squirrel wheel traps for bots as I have created very simplistic ones in the past that worked well against poorly coded bots and sometimes even crashed them to the point where bot operators would block my domains from being crawled. I do not have the skills of CF to make something more advanced like they did or I would and since I do not use CDN's I am on my own unless someone makes an open source version that can be plumbed into HAProxy or Nginx. I guess that makes me a skiddie.

A call to action Upgrade Plan for a Super Bot Fight Mode (pro or business) 2. The link to https://developers.cloudflare.com/bots/plans/ https://developers.cloudflare.com/bots/plans/ which does not mention (yet) of this new security setting.

> When these links are followed, we know with high confidence that it's automated crawler activity, as human visitors and legitimate browsers would never see or click them. Yeah, it would have been just stellar if I had spotted "huh, that's weird" in a page response and I chased it to see what it was. Then "har de har har, welcome to a Cloudflare blocklist, n00b" for being curious I hate them so much
- compootr 2y ago
  I doubt they'd add these protections for visiting a handful of links at human speed. Correct me if I'm wrong, but crawlers often send hundreds of requests per minute, testing random outlinks and routes they find on the site My concern would be as a webmaster: serving useless content to users, and as a user: not getting the information from the site. I probably wouldn't use this feature, since I often deploy static websites that use little to no resources, and the potential harm outweighs the benefit

Like burning down you house so squatters can't use it. A poisoning attack that makes communication itself untrusted. Wondering if we will get to extreme reciprocal mistrust eventually.

Making requests in bad faith is also an attack on communication itself.
- immibis 2y ago
  No? Not when the requests are served by a machine with the capacity to answer a hundred times more requests than are actually made. The only bad faith request for information is the one that wasted the answerer's time, which isn't usually happening here. It happens sometimes, but we're also trying to block the times that doesn't happen. Why?
  - rk06 2y ago
    requests are not served by just machine, there is also a huge network of wires spread across the globe for transmission. and getting bandwidth on that is pricey when AI crawler spams you
    - immibis 2y ago
      When any crawler spams you, but most bots do not spam you. They retrieve something at some reasonable rate. Btw cloudflare considers any browser other than the last few versions of Firefox, Safari and Chrome to be a bot. Such as Pale Moon. It blew up on Hacker News when CF demanded the PM devs to sign an insane NDA to get unblocked.

I'm still struggling with how you would address the bots that don't care for speed at all. How much do we care about stopping crawlers that are slower than the average human user? Is this even possible to do given perfect wire-level emulation of a typical UA? Should I expect pages protected by this technology to periodically Turing test me?

theamk 2y ago
this is explicitly "misbehaving bots" - it's for performance, not against scraping in general. A bot which is slower than average user is likely well-behaving, and therefore is out of scope.
Terr_ 2y ago
I imagine part of the problem is "fast" bots can be disguised as many many different slow ones, and it's not always trivial to figure out that they're all tentacles of the same malign being.
- malfist 2y ago
  You got to think though, that "slow" bot to you is a residential ip address hitting one or two endpoints on your website, but to the bot, it's probably doing this to thousands or millions of sites at the same time. Cloudflare is in a unique position to see enough of the Internet traffic to tell if that one ip address is browsing tens of domains at a time or thousands.

karaterobot 2y ago

I wonder how these hidden links interact with screen readers. The article says they only get served when Cloudflare already believes you're a bot, but due to my privacy settings and VPN, a lot of Cloudflare-fronted web pages think I'm a bot when I'm just browsing around the web. I suppose that having invisible links in the page wouldn't hurt me much, but would they bug someone using a screen reader? Honestly just wondering.

ericrallen 2y ago
Given the way accessibility is often an afterthought at best, this is a really good question. Would love to hear about some of the experiences that screen reader users and other folks who use assistive technology have with things like getting caught in the CloudFlare filters and other “human” verification systems. It seems easy to get caught in the net of “bot detection” as a normal user, and some of the verification steps don’t always seem very accessible.
- michaelbuckbee 2y ago
  Not quite what you're asking for, but Tor users have long complained that Cloudflare basically makes it unusable (asking for complicated captchas on each page of a site, etc.)
  - binaryturtle 2y ago
    I don't even use Tor, just an older Firefox. I'm no longer able to visit any site that uses that Cloudflare "human check". Once I whitelist Cloudflare in uBlock and reload to see the captcha the browser starts to busy-loop. Even closing the tab won't fix that. I have to hard kill the whole thing. I consider it straight malware whatever they do.
    - genewitch 2y ago
      I never let Firefox update when it wants to. I update it after Windows does so that everything breaks at the same time. I noticed that as my Firefox version gets two versions behind, I start hitting Cloudflare human test every single site I go to. Obnoxious. I like the extensions I have, thanks. It's my computer. It's the same fingerprint it was 5 minutes ago, and last week.

In this 'arms race', will this serve as an actual deterrent? Can anyone involved in scraping chime in?

yuvalr1 2y ago
I am not involved in scraping, but to me this sounds like simply another tool in the arsenal. They say it's hard for the scraper to realize it has been caught this way because it's not being blocked. However, I don't see anything preventing scrapers from implementing heuristics to realize that.
- pona-a 2y ago
  Detecting the actual AI generated content is not an easy problem. Not following deep links and recognizing the particular website template and structure is easier. I really feel a monoculture of anti-bot tools can defeat their effectiveness. When you have to optimize for Anubis, Nepenthes, Quixotic, and Cloudflare, each independently evolving and different in method and implementation, it might just be practical to give up.

The User-Agent does not provide a support link unlike their other bots." -- https://en.osm.town/@osm_tech/114205536438977922 https://en.osm.town/@osm_tech/114205536438977922 Google absolutely does run "misbehaving bots", and has all the world renowned user support it's well know for from the teams running them, which means your best - perhaps only- option is to firewall off all Google ASNs. With Google search's decline in usefulness and it's plummeting referral traffic, combined with their unashamed AI-grifting copyright infringement and IP theft, the tradeoff in the old thinking of "I need to let Google crawl my site because I still naively believe SEO will make my business successful" is rapidly moving towards "Fuck you Google, you don't get anything I publish for free anymore."

Wouldn't generating the content be much more expensive than the crawling done by the bots? How is it economical to deal with bots by spending a bunch of resources to feed them fake content.

palmotea 2y ago
They answered your question in the OP: > To generate convincing human-like content, we used Workers AI with an open source model to create unique HTML pages on diverse topics. Rather than creating this content on-demand (which could impact performance), we implemented a pre-generation pipeline that sanitizes the content to prevent any XSS vulnerabilities, and stores it in R2 for faster retrieval. We found that generating a diverse set of topics first, then creating content for each topic, produced more varied and convincing results. It is important to us that we don’t generate inaccurate content that contributes to the spread of misinformation on the Internet, so the content we generate is real and related to scientific facts, just not relevant or proprietary to the site being crawled. Personally, I wish they would have generated deliberately inaccurate content. It would be a further disincentive to do unauthorized crawling. Just as long as the inaccuracies don't intersect with typical "misinformation on the Internet" inaccuracies, I think it'd be totally fine and ethical (e.g. Queen Elizabeth II was the 34th president of the United States, the TV show Saved by the Bell aired for 14 seasons with the original cast, making it the longest running live action teen drama in Canada).
- TeMPOraL 2y ago
  Who would you want to target with this? Companies crawling the Internet for training data have enough of it to filter out such deliberately inaccurate content - if not directly, then by betting it'll cancel out in training due to volume of data. Now, if you want to mess with people who use LLMs to drive search instead of going straight to Google - what's the point? Just causally screw with other people? Why not also slash tires of their cars while you're at it?
  - theamk 2y ago
    Those measures target the AI companies that "misbehave", a.k.a. ignore robots.txt and scrape at such high rate that websites go down. The fact that their service may be useful to someone is not an excuse. Imagine hypothetical delivery trucks that violate speed limits in dense residential areas and occasionally hit locals. Would you want to stop them (maybe not slash tires, but fine the hell out of them)? Or would you say: "hey I really like the fast deliveries, so I don't care for a few fatalities"? Because your comment really sounds like latter.

MoonGhost 2y ago

The opposite of it would be an agent which deliberately generates expensive but useless requests. Like search. If it detects labyrinth.

threeseed 2y ago
But that agent would be making requests against Cloudflare's servers not the origin site. And that is a fight they are very comfortable in having.

KennyBlanken 2y ago

This isn't about blocking "misbehaving" AI bots. This is about blocking the competitors to the big boys like OpenAI and Anthropic. I help administer a somewhat active (10-20 thousand hits/day) site that sits behind Cloudflare. ChatGPTBot has been a menace - crawling several pages per second and going deep into site for years old content, which is polluting/diluting the cache. It also happens to be hitting a lot of pages that are very 'expensive' to generate. it also ignored a robots.txt file change for almost two full days. Yet...I try to crawl my municipality's shitty website because there are announcements there that are made nowhere else and they're too lazy to figure out how to set up email announcements...and Cloudflare instantly blocked my change detection bot running on my home server. It hits one page every 24 hours, using a full headless version of Chrome. BZZZZT - cloudflare's bot detection smacks it upside the head. If you think this is by chance or they don't know this is happening: bridge for sale etc. This is just more collusion with other large tech firms, working to kill each other's competitors, small services and sites, and innovators. Really cute, given half of SV got where it is by "disrupting" things (ie breaking laws and regulations - it's cool bro, It's An App!) Gmail will allow endless amounts of shit to stream into my inbox from "email marketing service" companies like mailchimp because I bought something 6 years ago from that company - but the second I need an email from a small community group mailing list that uses their own email server - a domain I've sent and received numerous emails to *and repeatedly clicked "Not spam" for - Gmail still keeps right on sending it to spam. I've checked. Their domain and IP range are both completely clean. It's simply Google saying "this wouldn't be happening if you were using Gmail for your domain's email." We desperately need to claw the internet back from these corporations or it will only get worse. Remember when you could run a web server on dialup and nobody fucking cared? Now you even so much has have port 443 open for some self-hosted stuff only you know exists and your ISP bitches a fit. Remember when you could use any client you wanted for services like AIM, but now we have Slack and Discord and they'll ban you for using a non-official client?

exeldapp 2y ago
I remember reading someone's shower thoughts that if the internet was completely safe there would be no need for Cloudflare, so it's in Cloudflare's best interest to keep the internet unsafe. It's an interesting thought even if a bit tinfoil hat-esque.

Cynical-me suspects step three is something to do with: "while allowing legitimate users and verified crawlers to browse normally." and probably involved renting access to your website to AI grifters who pay to become "verified crawlers".

  The best part about "verified crawlers" is that there's no easy way to discover how to become one. Or if you need to become one.
  - bigiain 2y ago
    Everybody knows how to become one. It's just like every "enterprise SaaS" out there. There's no 3 tier pricing plan with lists of features. You need to contact enterprise sales so they can work out how much you can afford to pay, then take all your money. And you _know_ if you need to become a "verified crawler", you just need to remember the developers you demoted or fired when they brought up the ethical problems of way you've configured your crawlers.
    - ccgreg 2y ago
      How does that second paragraph work? I run engineering at Common Crawl, and Common Crawl is ethical and has never fired a developer over ethics.

The US National Archives is a government agency. 1: https://eotarchive.org/ https://eotarchive.org/

Neal Stephenson's Anathem had a thing called "bogons" which were purposely misleading datasets.

It thematically relevant to the story, but it was never explained how they got there. I've been looking for a plausible explanation. I think I just found it.

I've been thinking about Anathem, and specifically that part of it - the Artificial Inanity programs, the bogons, the alluded-to war on the Ret - a lot ever since AI text generation really took off. It reminds me a bit of Watts' Maelstrom, too, although we're not there. (Yet. And hopefully never.)

bee_rider 2y ago
I think it isn’t a crazy thing to wonder about. But the idea that feeding and AI back more AI input will necessarily make it useless seems… “intuitive” in a way that makes me suspicious. Maybe it will be fine. There isn’t a known “conservation of sentience” rule, yet, as far as I know.

"It is important to us that we don’t generate inaccurate content that contributes to the spread of misinformation on the Internet, so the content we generate is real and related to scientific facts, just not relevant or proprietary to the site being crawled.” Can't wait for this to generate some liable content on a publicly traded company site. It's not because something is factual that it can't be wrong to communicate in context. Cloudflare has a habit of handing machineguns to toddlers in the name of antibotting, then shrug their shoulders and call it user error as they shoot themselves.

This Cloudflare article claims that "Medium estimates" that 47% of its content is AI generated, while linking to a Wired article that states the number is from an analysis from Pangram Labs, and is disputed by Medium.
