PS doesn't stack the deck against you. That would be stupid. That would be like blowing up a gold mine just to get the gold on the surface.
But cheating is rampant online. Anything involving money is going to have suspicious activity surrounding it. I've known a few guys that play the same game and are on mumble chat or ventrilo (voip utilities) and share card info. They don't have to coordinate play, just knowing more cards out of play than you do means you're going to get the snot beat out of you month after month.
Also, during tournament play a lot of stack dumping takes place amongst players making deals and taking percentages.
High stakes and low stakes you're probably not going to get cheated at. Mid stakes is where you're going to get cheated at. $.25 - $.50 you're not going to get cheated at. $1-$2 you will. $5-$10 you're probably not going to be cheated at (NLHE, PLO, PLO/8)
I play PLO, PLO/8 at cake poker. $.50-$1.00 blind generally and I do nothing but nut-peddle and I win very consistently. The reason being is Omaha is a more complex game than holdem and you can beat all the "statistics collectors" who profile you because you can change styles on a dime. You can't do that in Hold'em.
When I could play on PS or Fulltilt, I play 8 game and 10 game. It's difficult to get cheated in those games.
Warning though, I do no endorse playing poker on Cake or any other online poker room that accepts U.S players. You're money can be confiscated or very difficult to cash out.
I love Omaha hi/lo...we play it amongst our group at 1-2 nl. I I usually play WPT site. 19.99 per month...you win seats in satellites to play for bugger pots etc...not a true cash for play site.
I tend to agree. There's a lot of statistical software out there now. So it would be quite easy for anyone to monitor a site for house cheating. And once a house got caught, word would spread like wildfire on the internet. Then goodbye the golden goose (the house rake). I can't imagine a major site taking that kind of risk. Now, I sure do believe that there is player collusion, as you mentioned. And accounting fraud by the house itself, oh yeah. But house cheating on nickel and dime games? Not likely.
