I'm sorry to say both Cool and Lil', but your story is frankly an unbelievable one. Just to restate your claims:
Your sister had a birthday so a friend of yours came over and logged onto his account with your IP. He installed his hacked client and went onto our servers. He then got your IP perma-banned. Later, without knowing any of this, you try to get on to our servers but realize you are banned. So as a result, you think your friend did this and not your brother, so you scroll down to his account and remove him from your friends list.
It sounds like a sensible story... except for a few things that don't add up. Either "your friend" did all of the hacking without you in the room which would be strange because it was your sisters birthday and he should at least be with you OR he was with you during the hacking and you let him do such a thing on our servers. Next, we go to your good friend "yo mama". Before all of this, you were friends with him because obviously, like you stated, you had to unfriend him because he was harm to you. But this account you say you unfriended doesn't make sense with regards your story. Why were your friends with someone who had 0.4 hours in one game with no other games, no other friends, and was a Steam Level 0? Once again, it doesn't make sense. Lastly, like Death said, your story is unconvincing because not only do you and your brother have very similar profile pictures but you also sound very much like the same person.
With all of this said, I very much find that your story is bogus and deny your appeal for ban. I of course am not the final decision, but still I don't think you can hope that you will be unbanned. As shown above, everything points to you having done the hacking, and that is not what we want on our servers.
