I was there playing with my alt (Abudl Rashid Panbaba) and all I can say is that Onur is lying, Vitez kept going for the ballista, and Onur was griefing him by standing in front of the ballista, because he wanted to use it. Vitez warned him a couple of times that he may TK him, but Onur kept doing that, hence making Vitez rage against them.
Totally a troll/set up thread to ban Vitez, you can chekc the logs and you will see for yourself.
