Accepted I got false Guardbanned

My Steam ID: https://steamcommunity.com/id/gio136/
Explain what happened: so the warden ordered the reds to go on sweeper but then a sniper shot it they all thought it was me at first but after further investigation, they realized it was our other sniper (boh.) since I was killing some afks in cells but they accused me immediately since last round I kept hitting red's buttons in jeopardy so they thought it was me.
Later in another round (boh.) got banned for MFK I got a screenshot of it.

ah forgot to put the video of the report anyways its here as you can see it doesn't show who it was we can only hear the warden say that because they assumed it was me cuz what I did last round.
