I don't think so. I played there myself doing a
PSO promo and made a tidy sum and left the table. Never saw hands repeat themselves, you'd have to expand on that one. In fact, get the hand history and post them here! I'd be interested. Titan is part of the Playtech group which is one of the competitors to the Microgaming group that runs the Prima poker network. Titan is part of a network of rooms just like the Prima group and it includes Titan, Kiwi, and a few others I can't think of offhand (Noble perhaps?). Pretty doubtful its rigged.
Collusion between players on the other hand is always a possibility and if suspected should be reported. They will investigate.
