FWIW there were more people than crazyirishman involved in the argument in the technical thread. After repeated warnings in the thread, and in PMs, about the unwanted behaviour, he was given a temp ban. He then proceeded to create a new account and berate the mod. So even though he claims to have been singled out and banned without warning, that is a lie. I suppose the claim of censorship could be considered true, if you consider clenaing up arugments in a technical thread as censorship.
The fact is, there are very clear and concise rules about arguing and personal attacks in technical and on-topic forums. It's never easy or fun to ban anyone, and that is why we have a policy in place to give warnings. He chose to ignore them and escalate the issue. That's the facts.
