I read it, and it's not enough to make a judgement either way. For all we know none of this had anything to do with his ban and he was banned for something he did the day before. There's no way for third parties to be sure of anything in this kind of situation, where one party shares only the information they wish and the other side stays silent as a matter of default corporate policy.

I am not saying that the author was in the wrong and deserved to be banned. I'm saying that neither I nor you can know for sure.
