I care about having a good reputation and try my best to uphold it. However, without really knowing the situation or what your alias was when logged into chat I really can't comment about why you were banned from the chat. The last login with the name of "CrewRite" I see is below, since this was back in 2009 I doubt this is what you're talking about.
