Are there rules posted anywhere that help us understand why and how we can get banned on this site? I don't think so, so...fyi, am posting again, as there is no way this was "uncivil"....

You can get banned for a month from posting on articles deemed sensitive (which may be deemed so only after an hour or two, as was the case for the article on the London attack) if you committed the crime of disagreeing with the censors on whether a comment should have been censored or not...
