It's 3 AM, it's February, middle of the night, and you want to ban him for an AFTER round teamkill and some insults, some of which weren't even aimed at you?
His kick poll was in response to yours, you can't say he rage-polled you, since he could say the same to you. After-round teamkills should be limited to your friends and clanmates, but it's not serious enough to be considered a bannable offence.
No action taken.
