To be honest, personally, nothing he really said is all that bad in my opinion. However, I can just TELL he's an a$$hole. Not because I'm an esper or anything, just because I've been here long enough to see a couple hundered flame-outs.
So, in absence of evidence to the guy's good or bad character I figured I'd just join in on trashing the dude and it would only be a short while before he does one of the following things:
Standard insults:
"...the mom's basement you live in..."
"You play too many games, get a job."
"You're all just jealous/haters."
Then there is trashing the forum because we don't/aren't like eBay, Nintendo Age, Trump, etc.
Then there are just the straight up Nazis, the kids who think they're on a reality TV show about old games, and loser who moved to "retro games" from some other tacky hobby like sports cards.
I figure he'll reveal himself as one of those things if you guys keep f*cking with him. If he goes away...I guess we were wrong.
