Watch for people sitting down and leaving at the same time. When two persons are always in the pot together. They raise and reraise back to back to lose the rest of the field. They check raise and have their partner bet with powerful hands to maximize the pot.

Colluders are often difficult to catch. I noted this one hand and reviewed the history. They had several suspect hands even though they were only at the table for about 30 minutes together. Support should be able to review all of their play together. Many times colluders are so bad that they both actually lose money. They do cause alot of disruption to the game with their erratic play.
