@gme @thisismissem @iftas You do understand that a Trust & Safety organization dealing with this problem area is likely in a contract with and has tooling from NCMEC and follows this use-case rigidly, right?

Unfortunately, I think that’s the only way they could announce such a thing with any level of confidence. Otherwise, it’s a freewheeling DIY dumpster fire.

Like, you’re not wrong about the problem areas, especially with remote caching of content. Federation adds extra dimensions to an existing problem space. But these people aren’t just going in with willful ignorance. It’s not like they’re saying “okay, let’s build our own hash database, let’s go find some CSAM!”
