I have never experienced collusion. I leave it up to the sites to find it, and have never really blamed any of my losses on collusion. I'm sure there have been a few games where collusion was happening. But if you're playing small buy in SNGs, you don't have much to worry about. If there is colluders, it's probably two buddys, on instant messenger just telling eachother their cards. And if you can confirm this, by all means report them. As far as finding elaborate collusion teams, it would only be at the higher levels, b/c they would not risk collusion for some small change.

That being said, the odd pair of guys you do run into that are colluding, are few and far between, and aren't even really helping themselves much, they often are to scared to raise their friend off mid pair, that they won't steal pots from them, or pick up pots where they would have with aggression. It's really not a concern, where I play anyway (mostly on Stars).

I've gotten plenty of refunds from stars because of colluders. However, it could have just been due to stack sizes and coincidence? Also, some people just play overly tight on the bubble and they could have just not gotten any cards against each other. I know I have been accused of collusion many times in the chat box, which is absolutely laughable. If you really question it, just report the people and the site will be able to figure out if it was collusion or not.
