First of all, I wasn't unfortunatly there. But, I never saw Burak teamkilling on purpose nor teamkilling without an specific reason. Furthermore as an Admin you have to be thick-skinned, we're not in the kindergarden.
A perm ban for such 'insultiv' words is mostly unnecessary.
Banning people simply for the vague reason of 'trolling' is what causes a lot of unecessary resentment and unban-request workload on the forums.
I recommend an unban.
Yeah I was already wondering where you were, normaly when people "troll" or cause trouble you are not far away.
And i would recommend you start reading topics before you reply on them. No one mentioned he tked anyone on purpose. I barely mentioned he aimed with his rockets into melee fights and killed enemies and teammates alike the rounds before but I guess that is seen as coleteral damage. And if he gets tk'ed admins immediately have to act on it.
Insulting admins is against the rules, pretty sure of that. You should know Lyle, I think you were banned due to that for quite a while.
It also shows a pretty bad behaviour but heh, whom do I tell.
