Yeah, I think it's fair to say you won't be accepted at the school that caught you. And dreck is right, your actions could be considered criminal. As for being blacklisted at other schools, that depends on whether the school that caught you feels like notifying other programs. Also, if any of your actual letter writers found out about this I'm sure (or hope) they had the sense to withdraw their letters from each school you applied to and furthermore notify each department.
With that being said, I have to appreciate the hilarity of this situation. Did you really think you wouldn't get caught?
