Show HN: I built an app that scans every social media network for your username

I found myself scrolling through Github’s “trending” repos, looking for some coding inspiration. Within the next hour, I stumbled across something called The Sherlock Project. Interesting, It had over 35k stars, must be pretty popular. I quickly cloned the repo and started toying around with it. It didn’t take me long to realize the power of this tool. All I had to do was insert a username, and voila! I was looking at every social media website that was associated with the username. Not only that but direct links to the accounts. I immediately wanted to turn this into a web app so that everyone could use it. My first challenge was that this was a CLI tool, so I got to work. The Sherlock project makes about 400 requests to various site s to check if your username exists. This was going to be tough... I noticed they were using requests.FutureSession to multithread the result. I decided to use a multithreaded Web-socket to continuously report out data to the frontend. After ALOT of trial and error I finally got something working. The Issue now though was that it wouldn't run in production due to a multiprocessing error: Daemonic processes are not allowed to have children. Eventually I learned that you cant use the standard multiprocessing library for this kind of thing, you had to use billiard. Bam! It worked. I quickly hacked together a simple frontend, configured the web socket, and results were pouring in. Turns out, the web-socket is considered a "long running request" as it makes 400 external requests. Maybe I could use celery to offload this process to a worker and queue it up. I started working on it and realized this was a little out of my skill range. I then decided to take a look at the logs where I hosted the code and what do i find? CPU, Memory, and bandwidth all reaching a staggering 100% usage. I was using the free tier of Render that only allowed for one instance of my app...duh. I did some rework of my codebase and it started running a little faster. Needless to say, I learned to take it slow, build tests for my code, and be patient with results. What do you guys think? Any hard lessons learned in coding? What were your takeaways? Here is also a link to the repo: https://github.com/bnkc/handlefinder https://github.com/bnkc/handlefinder

  I think it would be useful to show the networks that the username cannot be found on.
  - Ostatnigrosh 4y ago
    Thats a good thought. I was considering it but was worried about "cluttering" the site
    - bombcar 4y ago
      Could be useful for people who like to “claim” their common handle.
      - veb 4y ago
        what I find annoying is that (other than HN) most places won't let you claim your username if the person has signed up, yet never posted over years (or even logged in) and places where an account was deleted. when I signed up to HN, I had a different username. I reached out to admins and they looked at the other account that had been created but they let me have it because the person hadn't logged in since. Oh! I think GitHub did as well. (shit, I wonder if I have mixed up GitHub and HN... I'm pretty sure they're the two that did actually let me have my handle... :x)
        mattl 4y ago
        That sounds like a bad idea. Why would it be a good idea to recycle usernames like that?
        williamscales 4y ago
        Because some people sign up for a site early and then never use it. I can't get my desired handle on a particular social network because some dude registered 15 years ago, posted one item, and then never used it again. I mean, obviously I'll live but it's a silly situation.

  The only username you should use more than once is your real name.
  - xeromal 4y ago
    I was 12-18 years old so I wasn't really thinking that way.
  - timeon 4y ago
    You shouldn't use your real name on the internet.
    - bombcar 4y ago
      Or use someone else’s real name. Like Abraham Lincoln’s.

        Negative. Only use your real name.

      For most people it doesn't matter much because there is many dupes. Mine seems to be unique, which is a little scary.

Great tool I used it to find all social accounts of my ex. Anyway, got to go as I am outside her house and don't want to miss her leaving for work. /s if it wasn't obvious. Cool tool.
- culi 4y ago
  good reminder for why you shouldn't use the same username everywhere unless you intend to have an online presence Personally I have a specific scheme I follow w my more private usernames. Basically the same username but depending on the website it has a predictable alteration to it so I get different usernames for different sites but don't have to remember them all Then I have a different username (well, a couple) I use for sites where I don't mind having a public presence that can be tied back together

You should also mention you are using Sherlock as the underlying backend which does that actual searching as you did in this post. https://old.reddit.com/r/Python/comments/z1ts1n/i_built_an_app_that_scans_every_social_media/ https://old.reddit.com/r/Python/comments/z1ts1n/i_built_an_a...

  Hey! Just added the MIT license.
  - bradknowles 4y ago
    So, you should cache hits. If someone asks the same question again five minutes later, then you shouldn't need to look them up again. Also, it would be nice to show misses -- where the account name hasn't been used. I have found a few other people out there with the same name, and it would be nice to know what systems I can go to and grab the name I want to use.
  - nop_slide 4y ago
    Apologies if I misread the license attribution, didn't want to take away from the work you did but also wanted to make sure credit was given. Cheers

And that's why I prefer making a username per site I use. No need to connect the dots, no need for this tool, except for spying on a person.

  Indeed. On that and a lot of sites I get false positives. Old usernames that I used (and pretty sure no one else did) on sites I've never visited.

Why use React for something this light? People wants to use a frontend frameworks for everything now, I miss 1998. Just kidding, great work! Way more accessibly to the average person than the Sherlock CLI. Also you have two requiments.txt's FYI.

great, it works (with some false-positive, like Enjin for example). A warning: an account could be suspended (since many still cannot let you remove it), and by logging in again you end up re-activating. just be aware
someweirdperson 4y ago
I am using an un-pronouncible combination of 4 characters in some games. Never could not get it anywhere I wanted it. Was surprised to see it found on 60 sites, none of them me. My username here is found on only 50, the other 49 not me. It might be a useful tool to pre-check names before creating accounts for someone who wants a consistent name everywhere.

Some people are liking the UI here, but it wasn't clear to me at first that a [+] meant the username was used on that site. In my mind, it could just as easily mean that it's available on that site (that could be a positive result if you're looking for places to sign up with a name). This should be made more clear. It would be interesting if you could toggle on the not-found list as part of the results. If you get a big positive list, but you'd like to find the sites where the username is not in use yet, there's no quick way to get that info.

I don't want to rain on anyone's parade, but I'll just add my unsolicited opinion... Functionality like this, and more acutely, any kind of cross-service, cross-account stylometrics correlation or de-anonymizing service gives me great concerns for its abuse and the groups that it likely endangers (and the groups it likely empowers).

  - nokya 4y ago
    Well, not sure I am a bad actor but reading the comment gave me the idea of typing my ex's nickname and I now discover she has an account on a quite unusual platform of which I am a member, too. For sure, I would never have the time to build such a tool. So, yes, some bad actors may have the "ability" as you mention, but I don't think that is the best justification to make querying this tool that easy.

I take this to mean that there's no evidence that username exists on that system. (And, I'm dubious that I'd have signed up at these sites.) * quizlet.com * www.enjin.com * apps.runescape.com * smule.com * livelib.ru And, fiverr.com's URL for my username just bounces to the homepage, as did any username. (Again, I wouldn't have signed up there.) Other than that, very cool.

(And, I'm dubious that I'd have signed up at these sites.) * quizlet.com * www.enjin.com * apps.runescape.com * smule.com * livelib.ru And, fiverr.com's URL for my username just bounces to the homepage, as did any username. (Again, I wouldn't have signed up there.) Other than that, very cool.

Lots of false positives
