Troll post or not - I think most people deserve a second chance. He might be outrageous or annoying to some but, it's clearly evident that others found him a welcome source of entertainment.
I say this from personal experience - being one of those types that has caused my own fair share of annoying posts and dramatic moments but, a little forgiveness goes a long way.
I've read some of the things that person has said and, to be honest that's not even close to the mean spirited or outlandish things I've said in my time here over the years. So if I am still someone worth having around, I don't see why that person can't be back on the forums. Unless his transgressions are worse than just excessive trolling - I saw nothing that was worse than anything I've ever said.
Like R-78 said it's Larva's choice but, that's just my two cents worth. Not even sure I was allowed to vote but, I did. Sorry if this is necro'ing an old post. It was new to me!
