Facebook is able to make very accurate profiles of their users. Maybe they should just send someone to the address of the uploader of csam and other horrible stuff to break their legs.

In all earnest, the fact this issue is as big as it is on their platforms is only because for some reason they let it get this bad. If they want specific stuff off their platform they can just make that happen.. specifically by targeting the sources... In cooperation with law enforcement and or nasty lawyers and a court summons.
