Website is shady afaik even Hufflepuff managed to scam PD -they finally figured out how this was done. Point being, there IS away PD can screw you if they chose to reverse engineer the Hufflepuf technique. I am sure they were aware of this long before. It's as soon as you start playing big bets the system gets you.
I read about this Hufflepuff "incident" and I don't really think there is anything to "reverse engineer" for PD as his method simply exploited some kind of server weakness, if you choose your own client seed everytime & verify our bet everytime I think you're safe, I remember another casino accused of cheating and even there if you use own client seed and verify every bet they can't cheat you.
