if it doesnt server admins can ban ppl because of personal problems
You didn't get banned for excessive team killing. If that's the message you get then there has been made a mistake. You got banned for other reasons, that refere to a post by you in the recently closed thread with the discussion about hslan etc. Thatswhy it isn't that difficult to guess where you got banned.
A little advice: I would be careful how you talk about other people in this forum. I wrote that 762 admins aren't very active here - that doesn't mean that they don't read the threads - and they do it carefully.
Get to the 762 forum if you want to know more details - other than that: good luck for your crusade on getting back to 762. You will need it and better find the right tone this time - just an advice
