I got kicked from a deathmatch server due to this:
Someone was throwing HE grenades in the spawn, killing them without them being able to fight back.
I escaped actaully go to play.
Now here is where it gets worse, I was lost around and I threw a grenade at a player, He was camping at spawn so if Anyone killed him, It could be spawn killing. I got him but a few people as well. Everyone started scream "KICK DEADFALL!"
I was kicked shortly afterwards. :(
