You could at-least do what I did, personally add the people you harassed/hurt on steam, make a long apology and send it to every one of them, mines even still on pastebin, and then I made a completely different apology letter on my un-cm ban, and I am still trying my hardest to prove that I have changed, I don't find it so hard to not break rules, and even if i did find it hard, I wouldn't do it to the extent of hacking or getting permanently banned again, apologizing is a very simple thing to do, coming out of experience, I did do the same thing you did, but now I proved that I have changed, in quite a swift passion. Proving that you changed, is much harder, being kind to everybody, especially the people you hurt, is much harder to do, I found it hard when I first got cm banned, I ended up being CM banned again, which you might find hypocritical since this is kind of the same situation since I also got cm banned twice, but I'm pretty sure he got CM banned for the same reason, where-as I got cm banned 1) for mass racism / rulebreak / minging and then 2) Leaking personal information, which in my eyes are different subjects.
Either ways I shouldn't of done these things, neither should have you. We do all make mistakes, but we also all do get a chance to prove ourselves, once, twice, maybe three times, but you must keep in mind, that it was once, twice or three times too many.
EDIT: I think I just wrote more and spend more time on this than your apology, which is quite funny, but I hope you learn from what I said and actually be a good boy this time, be glad that you didn't get re-cm banned bud.
