I can think of some things i could implement on the lemmy server side that could help with this, i’m pretty sure that the IWF maintains a list of file hashes for CSAM and there are probably a few other hash sources you could draw from too.
so the process would be something like the following
create a local db for and periodically (like once a day) update CSAM hash list
I would be very surprised if hashes for uploads are not already created, compare this hash with list of known harmful material
if match found, reject upload and automatically permaban user, then if feasible automatically report as much information as possible about user to law enforcement
so for known CSAM you don’t have to subject mods or user to it before it gets pulled.
for new/edited media with unrecognised hashes that does contain CSAM then a mod/admin would have to review and flag it at which point the same permaban for the user, then law enforcement report could be triggered automatically.
The federation aspect could be trickier though. which is why this would probably be better to be an embedded lemmy feature rather than a third party add on.
I’m guessing it would be possible to create an automoderator that does all this on the community level and only approves the post to go live once it has passed checks.
Say, if a crate implements the AutomatedContentFlagger interface it would show up on the admin page as an “Automated Filter” and the admin could dis/enable it on demand. That way we can have more filters than CSAM using the same interface.
I see.
So what do you think would help w/ this particular challenge? What kinds of tools/facilities would help counter that?
Off the top of my head, do you think

That sounds a great starting point!
