I was in a ranked game where our Mafioso decided to claim he was Witch d2 to Town when there was a confirmed witch. He got hung immediately. I have screenshots.
Here he is claiming he was witch to town D2: https://imgur.com/a/wIVLkfu
In the photos he openly claims Witch d2 to town, shows town voting him and hanging him, and confirming his username.
He then says he will just use a 2nd account if he gets banned.
