After reviewing your report and the evidence you have provided, I have spoken to Windows and he also would like this appeal to be accepted. The screenshot you have included in this appeal clearly shows how one of the traitors revealed to you how all the other people remaining in the game were all Traitors, which is basically a KOS on everyone alive except yourself, as stated by Miia. You simply took this KOS and followed it.
Thank you for making this appeal, the warning will be removed shortly. Enjoy your day
