You say he gives multiple repeats yet you're still standing in the doorway? You weren't stuck at the beginning of the clip meaning you could have still moved to the yellow line. This isn't a freekill at all. Report denied.
Since I can remember it being an accident, I'm going to give you the benefit of the doubt. I'm afraid this is your last chance though, if you mass freekill again you will not be able to appeal. Appeal accepted.
You were hiding in an spot that the zombies could not reach and delaying the round making everyone wait. You were given multiple warnings before getting banned and the ban isn't even permanent. Appeal denied. Wait it out.
Since I can not even remember muting you, I'm going to give you the benefit of the doubt. Don't micspam again or you'll get muted again without the option to appeal.
Then that is a terrible idea. You are asking "can I not be punished as hard next time?" No. The whole point is to dissuade people from rule breaking repeatedly.
