look resin. the fact is is that while you're right we can't prove that you and nix are the same person, it's a fuckload more likely that you are instead of all these coincidences. lets list them

1) your account been banned from another server (for same reason)
2) share IP w/ a VAC'd account (also, got banned from our server)
3) share a NAME with said VAC'd account


now, the only thing i will say in your defense is that it's a bit strange for you to return after about 5 months. but that's far outweighed by the other conditions
