Good point about the economics. My guess is the stars have other more lucrative methods for earning income unless it's just a hobby or whatever. I don't know anyone who will admit to paying for porn and even worse, the blockchain is forever so even free upvotes are um kinda difficult to hide.
Although now I can't help but wonder who has an alt account specifically for liking and loving and making porn?
Well, Im not hiding my main account here. I assume everyone is here of their own free will and that is the most important thing
