Use your powers as a private business to tell them they aren't welcome anymore. I'm calling on the Bike staff starting with Mo to get rid of these guys. Additionally, these guy are railbirds when they're not in play so they are always hanging around trying to get money to play. People I know have come to play there and then told me later that they had such a bad experience because of these guys that they won't come back. The Bike tournament staff know what's going on but they don't take any action. Then it's like you're playing against all of them instead of one at a time. The real problems happen when 2 or more of these guys make it deep. The dealers don't say anything, probably because they don't want to cause trouble because they argue with the dealers constantly. It's that they are constantly flashing their cards or telling the other to fold when there's a big bet or an all in by one of them. It's not that they bet others out of hands I'm not sure that they are smart enough to figure out how to do that successfully.
There's a group of guys who are regulars at the Bike (real degens) and when they play in tournaments the collusion is really rampant.
