Eeeeeeeh. There’s nuance.

IIRC there were only a handful of verified CSAM videos on the entire website. It’s inevitable, it happens everywhere with UGC, including on here. Anecdotally, in the years leading up to the purge PH had already cleaned up its act and from what I saw pirated content was rather well moderated. However this time the media made a huge stink about the alleged CSAM, payment processors threatened to pull out (they are notoriously very puritan, it’s caused a lot of trouble to lemmynsfw’s admins for instance) and so regardless of the validity of the initial claims PH had to do something to gain back the trust of payment processors, so they basically nuked every video that did not have a government ID attached.

Now if I may speculate a little, one of the reasons it happened this way is probably that due to its industry position PH is way better moderated than most (if not all) websites of their size and already had verified a bunch of its creators. At the same time the rise of OnlyFans and similar websites means that real amateur content has all but disappeared so there was less and less reason to allow random UGC anyway. So the high moderation costs probably didn’t make much sense anymore anyway.
