It's normal to get ban, he is not follow rules and he is ban, if you not follow rules outside a forum and get arrested, someone will forgive you?
And don't say that is mod faults, no one from moderators write from Corey account ...
Every moderator give his/her free time to manage forum.
Rules or laws aren't a purpose themselves. The main aim of a rule is to make the world better than it was before being applied. When the rules do not fulfill their main purpose we can speak of tyranny or lack of common sense, which is the worst sin of a moderator.
A question for you, any bolded and sharp decision like a permaban requires the agreement of all the moderators or is enough that one of you make the decision? In this case it seems that at least one moderator disagrees.
