I honestly believe that if you allow an online site to not only take your rake, but give your money to other players, they will do it. Think about it. If you own a poker site, you want as much money floating around as possible with the largest amount of players. That's how you make money. So it would make since to allow the good players along with the new depositors to win more. While causing the bad players, and addicts that will continue to deposit money to lose....
With that said, is the game random. Yea for the most part I believe it is, on the other hand. I do believe coin flip situations go more often to the good players that will stop playing when they are down. Along with giving the long shot wins to the bad players, and new depositors cause they want to give them a false scene of security. So when they run into a good player, and lose they will tilt, then redeposit. You cant tilt a good player very often, so why would you want them to lose to long shots, and lose their business? Knowing that if they are losing/not playing, you are losing rake. Then if they lose too much you lose, their entire bankroll.
something to think about.
