Night or 2 ago...
Shot him in pizza, was hiding behind a box and he came round the corner so he got a bullet in the head. I looked out onto the floor in front of me. He spawned in on the floor about 75 or so meters away. So he sat there until he un-spawned and i took him out again. So then he came back to my box area again. Tried to revenge from about <10 meters away and got him again. So by this point i know he is coming back again. I ran into on of the little holes in the wall (the entrance to a teleporter) and sat there watched him go by to get me. Then I popped out and shot him from behind. So then i called him on it. Telling him "No more of that" nothing else. Then he came back again and finally got me. I told him I had just told him to stop. Then i went and wrote 2 very long messages explaining revenge / assault. and he was a little ass about it and said something smart. I let it go... and tried to act nice, giving him "Good Shot". Didn't have any problems after that but on the other hand he didn't know what spot i was in, but he continued to run the map.
Might i add that he ends all his games with deaths in the 20-30's guess he doesn't care to camp...
Says really random things
And jumps in vent and goes down to the sniper server channel even if the lobby is fool (which is kind of weird)
and while in the channel he will not talk despite the fact that he says he has a mic.
