My only problem with you is the fact that you Dc / Kick without reason
Because someone kills you and then taunts your body is not grounds for kicking and especially not dc'ing them.
Do not threaten a player who is doing this to punish them unfairly or it will only cause a rise in whatever is being done. Instead stop what you are doing and whisper the person to please stop and if they persist either ignore it or leave the game.
