Yeah, so I got a copy of his PM forwarded to me, and it's not even an addon that he wants. He wants someone to help him modify the game client itself for a private server. He clearly knows that this is not allowed on this site, as the first part of his PM explains that he took so long to get back to the recipient because he was waiting for as many people to PM him as were going to, so he could reply to them all at once before he got banned when they reported him.
Cairenn, I can forward you the PM if you need proof to ban this dumbass.
