LemmyWorld forced to close shitposting community due to CSAM spammers - eviltoast
Lemmyshitpost community closed until further notice - Lemmy.World
lemmy.world
Hello everyone, We unfortunately have to close the !lemmyshitpost community for the time being. We have been fighting the CSAM (Child Sexual Assault Material) posts all day but there is nothing we can do because they will just post from another instance since we changed our registration policy. We keep working on a solution, we have a few things in the works but that won’t help us now. Thank you for your understanding and apologies to our users, moderators and admins of other instances who had to deal with this. Edit: @Striker@lemmy.world [https://lemmy.world/u/Striker] the moderator of the affected community made a post apologizing for what happened. But this could not be stopped even with 10 moderators. And if it wasn’t his community it would have been another one. And it is clear this could happen on any instance. But we will not give up. We are lucky to have a very dedicated team and we can hopefully make an announcement about what’s next very soon. Edit 2: removed that bit about the moderator tools. That came out a bit harsher than how we meant it. It’s been a long day and having to deal with this kind of stuff got some of us a bit salty to say the least. Remember we also had to deal with people posting scat not too long ago so this isn’t the first time we felt helpless. Anyway, I hope we can announce something more positive soon.

    Looks like some CSAM fuzzy hashing would go a long way to catch someone trying to submit that kind of content if each uploaded image is scanned.

    Not saying to go with CloudFlare (just showing how the detection works overall), but some kind of builtin detection system coded into Lemmy that grabs an updated hash table periodically

      Not a bad idea, but I was working on a project once that would support user uploaded images and looked into PhotoDNA, but it was an incredible pain in the ass to get access to. I’m surprised that someone hasn’t realized that this should just be free and available. Kind of gross that it is put behind an application/paywall, imo. They’re just hashes and a library to generate the hashes. Why shouldn’t that just be open source and available through the NCMEC?
