Can you explain in more detail? I just don't see the analogy you're drawing here. People may sometimes fence stolen items on Ebay, but you're not allowed to, and payment processors would definitely cut them off if you were.
Maybe that people may sometimes post illegal porn on OnlyFans but you're not allowed to either?
User-traded goods on e-Bay are also much harder to verify facts about than goods from a brick-and-mortar shop. Doesn't seem to prevent e-Bay from operating.
