I don't think it could have been the same exploit, because the system for generating dice rolls changed between the two events.
The sjess situation has already been discussed to death. The final position seems to be half the people think sjess should get paid because he was playing within the rules as stated and the site was coded as described, and the other half think he shouldn't because he found a way of winning, and it would affect their personal wealth negatively if he was paid.
Dean has said that he refuses to discuss this any further; the site is keeping the coins that sjess won.
