Considering your first ban was for 3 days for inappropriate language, I'm not really inclined to lower your ban. It's your account, you're in charge of it.

If your friend is real, he entered the scrim server uninvited, joined a team even though he was told we did not need a sub at the time, and then proceeded to teamkill all of the players on his team.

Any further incidences with your account will result in a much longer ban. I'll remove it for now.

Edit: If he's really your friend, I'd have a serious talk with him. Lying to your face is not the signs of a trustworthy person.

Do keep in mind, next time, you'll have to complete a formal ban appeal following our guidelines.
