Poker When does it end?

I am referring to the so called Variance, I play on 4 different sites, on three of them I have reasonable results win some etc, however on the 4th site, PokerStars I suffer from a long continuous losing streak, I mean I cannot win a race a flip or catch a draw, even with 15 outs on the flop, I just cannot catch, cannot win. This has been going on for approximately 37 days and that is playing 5 or more MTTs $1.50 buy ins daily. When I do catch AA or very good starting cards either no one calls or I get out drawn by garbage. I have read I should be patient and keep playing, however, when this goes on for such a long time and only on one site I am beginning to believe that the site in question uses algorithms to identify winners and losers prior to cards being dealt and if you are on the losing end of the algorithm there is no way out except to not play. Thoughts?
