There's no crime here. He followed the rules of the promotion.

Party Poker awarded points for making deposits. Matt deposited money. He would deposit so much money at a time (up to $50K) that he got bored clicking buttons, so he wrote a script to do it for him.

So, if depositing money wasn't against the rules and withdrawing the money after he got the FPPs wasn't against the rules, how can you possible claim that "this was a crime"?
