I know for a fact that the winner of the last Survivor Poker Event was cheating after a few games with him and indeed, he even admitted this to a Friend of mine. Unfortunately, in tournaments they migrate to the 5k rooms. Thankfully, they normally only do this in ViP where they get much higher RP.
You will also see that these 2 or 3 are usually the last remaining in the game. Another sign to look for is when 2 or 3 players play together all the time. Usually they tend to boost 1 person in tournaments tho not always. They do this to ensure their partner stays in the game. Sometimes they will raise against each other but you'll see that the winner will be the player with the least chips. The easiest thing to spot is that they will never go all-in against each other. You can tell after a few hands if you watch carefully. The way these people cheat in poker is 2 or more people mic up and work together. Funny you should mention that user Gamebling IE user name MILK_n_COOKIES.
