I would have to agree with the other admins here also. I am a head admin at Hackhunters, and I look though all the applications. If I were to look at you for getting into HH, I'd ask a question about it(maybe), but I'd look at the names, and I would find it highly doubtful that a player changes their in-game name that much from two different games. I would definitely suggest that you are clean.
I think that it is bs that other admins are banning because of linked IP's, especially when people have dynamic IP's that could be associated with anybody in your province(I think that's canada :P).
