Everyone who plays poker online shares these same concerns, so it's not surprising that the largest sites care deeply about their reputations (especially since they make so much money playing it straight up). That said, there has been at least one major incident where one of the original employees of a poker site used a "superuser" account to see his opponents' cards at the high stakes tables and win lots of money. The players figured it out based on his statistically improbable win rate and an accidental release of the full hand history of one of his tournaments.
