After watching the battlerecorder file and reading the chat in the logs files....
Capt-James.Coburn tked you without a reason.
He accused you of not doing your job as a gunner, which is false. Watching the battlerecorder file you were doing a good job as a gunner.
As you say, you reported him for the tk a couple of times and you did not receive any answer.
Because you did not receive any answer, you tked him back twice in a row and you were kicked.
Later on that round, James.Coburn tked you again and after you respawned, you started shooting his cobra with the AT kit.
Both were wrong.
You were breaking the rules too.
James.Coburn tked you knowing DangerousDoug could not verify the intentional tk, for that reason, James.Coburn is banned for a week now.
You will not be banned because at least you were kicked that round for you intentional tk and reported the incident.
But in the future, try to contact an admin help as you did, and if you cant get any admin help, report it here and we will take the appropiate actions, but never break the rules.
Thanks for helping us to keep the server clean of disruptive players.
