People quite literally still upload pirated porn. That's my point. It literally did not address any of the actual issues. It just got rid of pretty much all of their amateur content.
And as for the search function, it's not some bot. They simply banned certain terms, even if they're technically not even illegal. They did the same back then when all the fauxcest had to become step-family content. Funnily enough, most of those banned terms have a male bias. Swap the gender and it shows results just fine.
