Not sure if I'm allowed to post a link here but google for PokerScout and you'll find the site no problem. It's mainly just a review site for on-line poker but almost every review on the whole site about every poker room is just a complaint that the room is rigged.
Seems completely ridiculous to me, there's even less reason to rig a poker room than a casino considering they make their money from the rake regardless of who wins each hand... but then people will say that the cards are dealt deliberately to cause action - giving everybody a piece of the flop so that everyone will bet and the site makes the maximum possible rake.
I've been playing on-line poker for many years and had some horrible bad beats. I've also won a great deal of money some months too mainly from cash games but also Double Or Nothing's and winning the odd MTT. I have no doubt that PokerStars and iPoker are fair, so how can this site be 95% negative reviews?
