I am having a huge issue. The other day I was in world and a few perma bans came around. I was able to hear everyone and my mic went quiet. I re logged to people yelling at me that Racial things were coming thro my mic. This was NOT me . This lead to a 10 day suspension. I log on last night and they tapped into my mic to play racist things again. What can I do to protect my mic??? Or is there no way???
