Y'ask me, making a new thread was just way over the line. It was disrespectful when an already sensitive/potentially volitile thread had been locked. Making a second thread about it went well past that. The temp-ban was warranted. Then creating a guest account to get around the ban? Yep, no problem with that, either.
Then again, this kind of behaviour I would expect from someone else who had done that several times before.
