It's just small step.
For example this guy have 720 vids, 600 of which are asian and maybe half of them looks like from 1 paysite.

I've heard Megarotic is banning accounts when Copyright owner contacts them. Unluckily, vids are probably cropped to hide watermark.
Anyone knows from what paysite they are?
