The "rigged" theories/question have always amused me. I always wonder what they mean by "rigged". Perhaps a faulty RNG? Maybe mulit-accounters/bots/house players running the poker sites? Super Users that can see your hole cards? Or a combination of any of these. LOL don't make me laugh....
I don't think it is "rigged" There is variance in poker like in sports. Think about the NCAA tournament and the upsets each year. I know online can be frustrating, but poker isn't won in one hand or one tournament. The game of poker is a life long game.
