Yes. But the problem is and always will be who decides what crosses the line and not.
*** to be clear CSAM BAD ***
I think of the people who got the lives ruined because a person or a machine marked content that was mistakenly selected. If an npub gets publicly listed a pedo because of a mistake a machine or a reviewer made, that's a big deal. However I do understand this number is likely to be much smaller than the number of actual pedos sharing content. Who gets to decide, how does an appeal work. How do we handle reputational damage? How do we handle mistakes (even in code) with a public pedo registry? Do we do it like most western countries handle pedos?
Governments are going to do this if they aren't already, maybe we the despot's do what they were going to do anyway?
