Alright, this is all pretty stupid.
Raxmus and goresaw, your bans are extended to be approximately 12 hours total since the time you were originally banned. That'll be approximately 9 1/2 hours from this post.
You were definitely closing the gate on offense, that much I saw. If it was a mistake, your behavior in the screenshots and videos doesn't support the idea. You also did not respond when I asked you a question in pinktext, so that's not very helpful, either.
I'll look through the logs for the "more than 10" teamkills you say happened to you. I'm skeptical about the circumstances of those, however, especially if the amount you claim is true. Typically a player is incited to break the rules because of the actions of another player, and griefing an entire team like you've done is a fairly common reason for doing so. That does not justify an additional infraction, of course, so if there are clear misdeeds to be found in the logs the proper parties will be punished as well.
Don't close the gate when on offense, don't close doors when on offense. Don't teamwound intentionally, not even your friends. Don't even kick teammates! You don't see the threads about people kicking teammates and receiving punishment for it because you seemingly haven't looked through the Closed Requests subforum.
