As I read it, the Feds could go after the online pros using the RICO statues...and go after their personal wealth. The foundation for my statement is that the pros, Ivey, Dwan, Negreanu, etc. personally benefited from the activities of the sites that sponsor them. If PS and FT are successfully prosecuted, that establishes that the sites violated the law. And, part of the profits from that illegal activity was paid to the sponsored pros. Thus, although the pros did not violated the law themselves, they profited from the illegal activities of others. Therefore, their "ill gotten gain" is subject to forfeiture. And, if the Feds can show that the pros should have known that they were working for a company who was violating the law, then there could also be additional fines and penalties the pros have to pay.
