Wasn't the attacker on PD only able to withdraw 40 btc before his misbehavior was noticed and all his other withdrawals were blocked?
On the account where he was obvious about it, sure.
I wonder if he had other accounts that he used before that, where he won a bunch in a less obvious way?
The way that guy acted out , making straight flat bets at 50% and winning like 100 times, was probably his way to reveal the bug or show that he had hacked the system. I don't think, someone who could have found the flaw would make such bets. He probably hit PD before that Big time.
