Ah! It's a conspiracy thing!
From my viewpoint, Jason built his site with a different model in mind than many of the more commercial sites like this one. RCCanada appears to be modelled on the social environment, kind of like the rec room of the 70's. Although not everyone may agree, and have different methods of verbalizing their disagreements, everyone is expected to to respect the views of other. When someon gets out of hand, and it's drawn to his attention, he has to evaluate if the parties involved are simply blowing off steam or are truly there to cause trouble. When a dispute arises, and you find one participant has a legacy of posts with a particular theme (Sh*t disturbing), I suspect it's a simple choice. I do know ... he warns you before booting you.
