Ask HN: Dealing with users who share child porn?

  The EFF may be able to help you. I would prepare a document with the logs/info that you have in addition to a copy of your privacy and data retention policy. You may also want to doublecheck to see if the submitter IP is a Tor node, that'll make everyone's lives easier. I believe the FBI has a special taskforce for this should you contact them.

    Headed to the EFF branch in SF tomorrow. Thanks for the suggestion.

      EFF wasn't much help. They gave me a brochure of their services and told me to email them.

  I run a couple of short URL websites and this kind of short URLs along with links to phishing and spam sites is what you'll get on a very regular basis in this business. Those short URLs are often being used in mass mailings, guestbooks, comment forms etc. and they'll get reported pretty quickly to URL blacklists. That gives you the chance to disable the shady short URls before too many people come across them. Here is a list of URL blacklist providers that you should check each URL against, both before accepting it into your database and again before you deliver it to the user: multi.surbl.org, uribl.swinog.ch, dbl.spamhaus.org, url.rbl.jp, uribl.spameatingmonkey.net, iadb.isipp.com, dnsbl.sorbs.net You can find out more about this stuff on http://www.surbl.org/ http://www.surbl.org/ Since I've implemented these checks I only receive complaint emails every other month and no contact from the authorities so far (in contrast to the disposable email services I run). When you get a complaint about a URL, your software should allow you to disable all the URLs of the reported domain. There are times when the spammers have taken over a forum (or any site really) and created a large amount of spammy content. Hope this helps.

    Thank you - I'm going to check out those blacklist providers. I have the ability to disable by host; up until now I haven't had the need to exercise that feature.

  {Random advice from the internet} My first thought is to wonder why someone would want to be in a space where an arms race against people devoted to child porn was both necessary and constant. Particularly when that space wasn't providing capital sufficient to retain a lawyer. My gut tells me that as a matter of will, it's going to be hard to keep this class of activity from reoccurring regardless of how this incident works out and that scaling the service will scale the headaches of monitoring and policing user behavior along with it. Personally, I'd rather deal with users I liked. YMMV. Good luck.
  • chejazi 11y ago
    Thanks. We're working on ways to secure the capital for things like retaining a lawyer. It's not the fault of the space itself; our business model hasn't been fully executed. As to it being an arms race, I'm not sure the techniques to filter content are really competing against anything. Sure, it seems like there will always be more sites to ban, but its not like adblocking, where the tricks are getting more sophisticated over time. Also, I like (most of) my users! We've had some spam issues in the past where users created minor headaches, but this was a first.

  If you store photos, Microsoft has a free product called photodna that will match filed against illegal images. Take a look at the Center for Missing and Exploited children and perhaps call them. They operate a tip line to report this kind of activity. Sad that we need to think about these things.

    No photos stored, just links. Thanks for the suggestion!
