as lothar didnt answer yet ill just try to give my quick opinion, i cant ban them though.
i checked all screens, double checked and tried to find connections like chat messages. Some DKG are known for stuff like this but that can't be a reason to ban ofcourse. You need proof and unfortunally only this screens shows evidence AND a name
there were atleast 3 DKG's online (judging from the screens) so its not possible to determine wich guy is wich on the other screens.
however this one screen can tell us there were 3 tks
-nukkel kills terence
I accidently killed DKG guy. I was about to say sry.
My teamkill was not internetional
i think that was no accsident
-kaese kills nukkel
but then kease came and killed me.
but i said kaese let it be and dont kill nukkel but he do it
-ghost_pl_46 kills kaese
But then the other guy helped me and killed DKG.
Seems like kaese indeed tked on purpose. ghost 'helped' nukkel by killing kaese, however this happened after nukkel was already dead.
I would like to remind everyone that teamkilling someone because he teamkilled you or another person before still counts as revenge tk. Take screens and post them on this forum, as long as somebody is not team attacking you you have no reason to fight him.
