Hi, just to clarify, the guardban timer only goes down when you're alive on RED, it doesn't magically count down when you're away from your computer, that's just how the guardban timer is set up to avoid exploiting and avoidance of punishments, such as yours.
That being said, you have served a substancial amount of your guardban and it was from quite a while ago, so I've gone ahead and lifted your guardban for you. You should be able to freely join the BLU side the next time you join one of our servers.
Do bear in mind, that if you receive any more major guardbans, they will be very difficult to appeal for.
Appeal accepted.
