Regardless of the lack of template: I will proceed to deal with your appeal.
As far as I remember, I brought you up to a roof once for NLR. I don't believe in second chances, since I told you once, you shouldn't have the mental capacity that you would proceed to do it again.
Here is the rule documented about NLR:
NLR is where you are killed by a player in an RP situation. You can't return to the district of your death until the timer at the top of your screen reaches zero.
The district is basically the group of buildings on a street or a tunnel. Do not loiter these areas, and even after NLR you will not be able to remember the circumstances of your death.
You engaged with the mutants upon exiting the spawn: had you not done this and you moved on to leave the district, I wouldn't have banned you.
You can wait out your ban (24 hours).
