I think he can do whatever he want since its his company..
Butttt! he does not always "ban" the provider for ever orso.. but understand that if you lose a lot of money on a provider it ain't that much fun to lose alot of money on a provider.. I remember my friend bought 47 bonus games on Mental (gamble future) so where you can get teh 50/40/10% and he never got the super bonus 10% in all those buys.. yeah that's kinda rigged if you ask me or just bad luck i don't know!
but i know one thing and that is that they are trying to let people enjoy everything they stream. but they can't always make everyone happy.
