MODERATORS
 

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: @[email protected] 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.

Something I thought about that might be helpful is if mods had the ability to add a post delay on a community basis. Basically, the delay would be moderator adjustable, but only moderators and admins would be able to see the post for X number of minutes after being posted. It'd help for situations like ongoing attacks where you don't necessarily want to have to manually approve posts, but you want a chance to catch any garbage before the post goes public.

Edit: and yeah, one of the reasons I'm aware that perceptual hashes can have collisions is because a number of image viewers/cataloging tools like xnview mp or hydrus network use hash collisions to help identify duplicate images. However, I've seen collisions between unrelated images when lowering the sensitivity which is why I was wondering if there was a way to use multiple hashing algorithms to help reduce false positives without sacrificing the usefulness of it.

Or just making posts approval only with a mod queue
