I mean, one solution would be to not allow photos on that instance. Just spitballing, because I can’t think of an efficient and ethical way to go about screening image uploads, that doesn’t involve some sacrificial moderator being waterboarded by human perversion.

Maybe, using AI? Can a locally hosted AI instance scan images? I might host a lemmy instance in the future, because I want to support the cause, but yeah, I ain’t going to jail for it.
