I must admit, I'm surprised this didn't end up in a blood-fest.
For those of you who want him to come back, you'll need to take that up with David. Dudemcbob has been told the same thing. In the end, only David can override the decision to unban him.
On the request of the OP, this will be locked.
{Edit} I have gotten a few PMs about it already so just to fill you all in. I am aware that Dudmcbob has a new account. He has made it purely to talk to David and he knows what will happen if he is seen posting in it.
