CriosPhilemon caught exploiting on video

https://www.youtube.com/watch?v=Em93DIC5XzM INCASE THIS WASN'T ENOUGH EVIDENCE

He was in the brown building with no door the gunshot came from behind me, and as soon as I pass it in the video, I die, and you can tell he didn't kill me from behind because there was no one behind me after I killed the zombie, also, at 0:10 you can see some zombies in the corner, they would've went agro since there was no silencer. Over the past hour I was arguing with him, he got no zombie kills, how is that possible while traveling in Kin, where plenty of zombies spawn? After I showed him the video he left the server. Please make sure something gets done about this.
