Theory about online cashouts

I played at absolute poker a few months ago and I did pretty well at first, winning 243 dollars the first time I cashed out playing 10 dollar sit n go's mostly. After i cashed out i tryed again to build my bankroll up the same way and it seemed that i was always caught in bad situations, QQ vs KK all the time, took horrible beats, QQ losing to Q3 off and the guy getting four flush cards. I also seemed to see the quality of my starting hands go down. i read on the internet somewhere that absolute poker is run by crooks who totally screw you every time you try to cash out, that the same thing happened ti him. I saw something similar to this at pokerstars. Is this a reasonable concern/theory or am I just buying into a myth.
