He's been banned so many times. Every time he asks for another chance and promises to do well. Every time he also gets banned again. Give me three legitimate reasons as to why he should be allowed back, and then go for it. Because from my point of view, causing arguments constantly and ripping people off with low quality parts are pretty good reasons to get banned. This site's better off without him, imo.
Plus, I think I gave him a three month ban? I don't remember but I'm pretty sure it wasn't permanent. He should have to wait just like everyone else.
