I don't play here much anymore. I did play recently, though, and found out upon cashout that I basically owed them money because of previous so called "super sticky" bonuses. They removed more than the uncashable bonus from my withdrawal, they withdrew 3 previous uncashable bonuses from my withdrawal!
I,too, cashed out some fairly nice wins in 2008, none since, until this recent one. The cashouts were successful.
