It seems unjust at first glance, but I can see why hes going to remain permaed.
I understand your aggravated because you were banned, but you Honestly didn't have to try to win your spot back by calling the admin's ban an act of friendry.
I'm on Daenth's side but I'm being reasonable here, If it were me I would've asked if it was accidentall before jumping the gun and perma banning.
The retaliation is what makes me understand Killer2's decision afterwords.
Still Gravity cat must be REALLY strict about team killing.
I would ban for excessive or frequent team killing. But it was vehicle Team kill, and if you've ever spent enough time in a vehicle TDM you know its bound to happen to anyone.
