I just got banned by this "ruplayer" on the map de_dust2. The reason for the ban is harsh or inappropriate language directed at ruplayer on the previous map nuke.

My side of the story: Playing on nuke (I am ct to start and he is terrorist). About three rounds in I pick up the awp and start doing really well protecting heaven and outside. Got a few MVP's and what not, just having a good time.
SIDE CHANGE
On T side first round, I along with a few others on my team are pushing the outside area. We end up getting flanked and long story short, ruplayer kills me from behind. He tells me something like(I don't remember exactly what he said and I cannot go that far back in the console) "Do the objective and stop camping on attack."
So I said "umadbro?"  This is my mistake of course. Any time anyone asks umadbro to someone else its automatically a yes because its just troll talk. So I keep talking to him and he then tells me that I was not doing the objective(when there are other players that come on all the time and don't know the difference between a pistol and a hostage) and I was not with the team. Then he banns me.

TLDR. ruplayer gets mad that I kill him a bunch and talks shit to me then I talk back and he bans me for not playing with the team and doing the obj.
