He was friendly and didn't bothered me. Just once, but that was a while ago.
I'm afraid its this kind of attitude about his wrongdoings that got him a free pass to being an asshole for so long. He did indeed bother you, even if it was just once, and even if it was a while ago. He tormented many folks before and after you.
Many people just assume if someone is nice to them that they are a nice person in general. Even serial killers can have normal relationships with a few around them. (Not that i'm comparing him to a serial killer, i just study serial killers)
Back to the point, this guy was a professional at fooling his target market. He knew what pics to post, what gay percentage to claim, just how to be nice to the ones that aren't likely to get involved in problems around here.
He knew just how to get support and obviously get his goals acheived when pissed off. I've always wondered if he was an alter ego of an appearingly upstanding moderator.
Pieter, even if he was only mean once and a very long time ago doesnt negate the fact that you might have been totally wronged by him. I know your personality and you are a very good guy. You arent one to fight with people. So its people like you who all the more need to remember people like Monster. Maybe if more of us stood up for ourselves when this happened he could have been banned long before now.
