@kissane I'll be upfront about the fact that I haven't read the report bc I don't have the energy, but from what I've heard, the vast majority of the servers they found the CSAM stuff on are already defederated by everyone, they're on the Tier 0 blocklist that instance admins use basically verbatim to get started. And there's nothing anyone can really do beyond that, because Mastodon is FOSS. We can't actually stop horrible people from making horrible instances. So I don't really know what the point is of saying that you can find a small number of instances that are mostly walled off from everyone else that have CSAM on them. It's like complaining about the internet as a whole bc some people are hosting bad shit on it.
@anarchopunk_girl Most of the CSAM is already walled off, but quite a bit wasn’t, even in their tiny sample, and they had pragmatic technical suggestions for strengthening protections. Especially with fedi’s rapid growth, that seems crucial to me. I think the report itself, which I’ve read, has been misrepresented here bc the press was uninformed and just bad, but a lot of good admins are paying attention.
