I talked to Doombringer about some of this and it turns out you were not muted, that was a complete lie. From what I have seen now it seems you were bugging him in an attempt to frame him for randomly muting you when he never did. You also didn't include the entire story of how you acted and pretty much most of what you wrote seems to be lies now that I am more informed. At one point you followed him around the map shouting; "Demote Doom".
You were never muted by Doombringer and just plain lied about it. This is disgusting thing to do and I hope it has some serious consequences!
