Collusion is done carefully, several nicks and not used daily etc.
And don't let every nicks results fool you if the are not 20% ROI.
For example CACEMPOKER. Below is his Don history. These games are consecutive games. Pay attention on how rarely he plays, yet against the same players every time from the list of colluders i named in the beginning of this post. Same goes for every of the 20 colluders.
Same kind of example for ocidenseg. I can show the same for every player.
These nicks go back very far so it has been going on for long. It is possible there are more players involved in this. I've been running horribly in the DoN's so i started to investigate a little.
I reported this to Ipoker just now and i ask or you to do the same. Just copy paste this whole text or link here. Thank you.
