2 things.
First of all brock does have a history of leeching, I've warned, kicked, and banned him for it before.
2nd dicking around with an admin you know is one thing, but teamkilling an admin that you just badmouthed cause he banned your friend is a completely separate issue. That was way over the line and you know it buddy. Considering you have a recent history of Tking bans, a 2 day timeout is quite light.
