I may be reaching here, but the post you made in "Introductions & Farewells" kind of kills the credibility of this statement. If you have really changed, then I don't think you would make a post about CTs getting arrested with a Ram Ranch parody. This makes you look like you haven't changed in the slightest and only intend on getting in more trouble. Yes, it may be a meme but it's probably not something I would personally have up if I wanted to make a case for myself being unbanned.
If the High Staff team can look past this, then all the power to you, but anyone can just say "I've changed". Your actions speak louder than words, and if it's too late, then it's too late.
