Pokermonger is right.
Casinos have tried for years to get rid of duplicate accounts – it has just resulted in more sophisticated methods of doing this.
I know for a fact that there are groups of players roaming casinos and collecting bonuses with multiple accounts and they are not getting caught.
Of course I am not going to publicize how it’s done either, but believe me that the casinos are thoroughly fooled.
I do know that there are also a lot of poker bonus abusers out there. I am told it’s much easier to do with poker.
Thanks Ellen. 
I think in view of Party Poker putting a stop to rake back they are also working the affiliate system over in some ways. I am not sure how it will end up, but maybe Satya is not ready to comment. Elsewhere in the Iglobal forum he said that soon there will be an announcement….
That said, the remark about the new account having to be created is scary…
