Like DTN said, your chat logs would be a pretty big help in your case - definitely a better help than snidely claiming that you'd rather play DOTA.
And, what's there to review outside of your behavior? Is this just another one of those "I flamed a flamer and got banned" kinda posts? 'Cause those often end the same way - people getting told that flaming someone back after they started is just as punishable as the other guy starting the whole thing.
Either way, without associated logs, we're all mostly left to assume that you were banned, and therefor in the wrong.
