There are some that can be forgiven but that does not necessarily mean that they should have a place at the table.

There was one player this year that did something that to me is very destructive to the hobby. While he can be forgiven, I am a strong advocate that no one should ever buy from or sell to him again. Some people can be redeemed and others need to serve a reminder to others what not to do. That's why some people in the real world go to jail for life.
Yes, we've had some real winners here in the past. Threats of violence against boardies, crooks, thieves, scammers. Remember the guy who PMed comicdonna that he was going to shoot him in the head? How about the guy who went to jail for rape. He was an ex-cop. Those examples are extreme and while I am all for redemption for those who show they are worthy of that redemption there are some people that should never be allowed back.
