Firstly your admin in chat was on a mission to purge the server of people not following the rules I get that.
BUT THIS IS WHAT HAPPENED
I confronted two players with my pistol and killed the first and ran away, the player I killed was in the process of throwing a grenade (M67) which was dropped as live once I killed him, this in turn killed his team member and counted as my kill, I was about to type in the chat that I didn't use and grenade as I use incendiary anyway but I was banned before I had the chance. Which is unfair as I saw the admin in the chat give someone else multiple chances.
Whoever it is, calm your ego, its not my fault someone else died to me while using a grenade.
If you unban my username is the same as this account
