Kicking teammates in the spawn causing one person to try and teamkill you(as in the account), then continuing to kick him after you were asked to stop wasn't smart. Leaving shortly later and switching names just to rejoin, take aim, then shoot the admin that slayed you in the head at the spawn, then leave is an even worse idea.
It has been a few days so I will unban you, should be able to rejoin within the hour.
Be sure to reread the rules as to not be banned again or next time it will be a longer ban.
