Collusion is when players team up with each other to cheat other players. Active collusion means that players will actively work with each other to juice the pot when one of them has a winning hand. This type of collusion can range from a novice level to a highly refined level that is hard to detect. You can spot amateurish collusion when two players get into a raising war with each other and either drive all the other players out or string a caller along, then one of them suddenly folds at the end of action. Or, one of them might even go to showdown with absolutely nothing and show it to the table. As stupid and obvious at this seems, it does happen. Don’t be prepared to jump on the person immediately for being a cheat however. Many times, some players simply are complete maniacs and raise anything. After watching their play for awhile, the timing of their raise should raise eyebrows.
In the event that you honestly feel like you are playing with colluders, your best options are to leave the table and remember not to play with those players again or live chat a floorperson and notify them of the situation. If the floorperson is too busy, then email support and tell them of the situation also. In both cases, present the facts and try to keep it short and concise for the best results. Screaming and yelling about how you were cheated definitely hurts your chances at getting the colluders reported.
Passive collusion is when players work together only by sharing information that may give them an advantage over the other players. This is usually simply sharing their hands with either other, through instant messenging or cryptic messages. Online, this type of cheating is almost impossible to spot because there are no tell tale signs of passive collusion.
