For player customs that you pay.. with in-game currency. Yes, some people buy packs to pay for their customs which generates some kind of revenue. But you got to think, not everyone buy packs and actually earn gralats from doing various jobs. but then again Graal as a whole is copyrighted from the old Zelda. And still with the upload rules enforced, some uploads do get through without notice. I honestly don't care about it, but if Graal is going to enforce something keep it that way. Don't try and twist the knot.
