Okay, to sum up what happened which lead to your guard ban, I will reply.
When you went warden that round, you were doing True or False day in knife pit. You had set red to false and blue to true. You then asked the question in chat "Sniper was born in Australia". All of the reds except one had entered the red side, which was the correct answer, as Sniper was born in New Zealand but raised in Australia.What you had done after that was open the red side and kill every rid inside, despite the correct answer. You had also killed the one who had, in your eyes, gotten the question correct.
This was a lie and a mass freekill. I also added in the part of you mumbling into your mic constantly when giving orders to mask up any mistakes you may make and therefore get off Scot-free. The round previously, many people had told me in chat that you had freekilled them, but I wasn't paying attention for a moment and so I could not punish you.
