Pornhub execs can go to jail if they don't remove stuff that is illegal and prevent sex trafficking on their site. Facilitating and distribution itself is a crime. PH isn't a government prosecutor they have error on the side of caution and due process is right you have with the government not a private business.
Women in the videos that Pornhub is profiting off of could be sex trafficking victims. They have taken steps to stop sex trafficking but that was more of the government threatening to shut them down and/or jail their execs.
