CURRENCY EXCHANGE
Shak would offer to exchange currency for you at market rate, for seemingly any realistic sum. It would take weeks to get your money if you ever got it.
FLOATING ACTION
Shak would buy your action, but not pay you for it unless it got to a point where he would lose that action unless payment was received. It was often that players would get paid if they made it to a point where they were likely to cash.
GHOSTING ACTION
It’s believed that Shak was overselling for some events, and then punting off his stack. I also know he was offering different packages to different people, and wouldn’t play all the events.
SELLING SIDE ACTION
Shak would buy a package from someone, and then sell %’s of his action in that player to others. I’m not sure if he actually owned the action he was selling or not.
SMALL LOANS
Shak would borrow money from players to play an event or cash game, and then disappear. The debts would never get repaid.
FAKE BANK DEPOSITS
When you required money to be sent prior to you sending, you would get a picture of a fake/doctored bank draft and money would show up in your account. It would be removed days later when the transaction bounced. This was always somehow the banks mistake.
