How about policing CSAM at all? I can still vividly remember firehose API access and all the horrible stuff you would see on there. And if you look at sites like tk2dl you can still see most of the horrible stuff that does not get taken down.
It's on X, not some fringe website that many people in the world don't access.
Regardless of how fringe, I feel like it should be in everyones best interests to stop/limit CSAM as much as they reasonably can without getting into semantics of who requested/generated/shared it.
Do yourself a favor and not Google that.
