If Joker2 and his "squad" did cause the mute ... then HT has the logs.
Rather than bring it here, it probably would have been better to email HTC explaining what happened ... they could then go back thru the text logs to see what really transpired, and if he and his "squad" were in the wrong ... I would think that they would get a talking to by someone at HTC.
In the 6+ years that I have been playing this game, it never ceases to amaze me the seriousness that some people bring to this game.
