If it's infeasible for the business to operate ethically, the business shouldn't operate. But the resolution isn't impossible, especially for a company of MindGeek's scale: Remove anonymous uploads entirely. Require channels establish their and their performers legal identity (which for monetization, many have to do anyways), and require metadata on all performers in any video (presumably allowing them to publicly display as anonymous or with a stage name as adequate), and verify the consent of those performers to be posted on that channel.
