If your account is idle for sometime or closed that is one way around it. I signed up for rakeback through pso back when they offered it. Then they stopped tracking it or whatever so i didnt play there. Now that individual tracking is available again maybe my old rakeback account will be good again.

Also im sure plenty of people that live with a roommate or brother or father or whatever are just going to signup new accounts. To much money at stake for high volume players.
