Betty, Midway being muted can't be false. I think Einstein wrote a theory about it. 
Not sure what I said to deserve the mute and I did send an email to the support address to find out. I said nothing remotely involving cursing or name calling. I do admit to pushing TwinBoom's buttons, in fun, he being the enemy, knowing he couldn't respond due to probably being muted as well, and did enjoy the subsequent fights and resulting pwnage he laid on me. Many have disparaged my fighting and choice of aeroplanes plenty so I considered it routine joshing.
Having been involved on the other side of this with others, also while I was muted to where I couldn't respond, I did not think what i said was a mute worthy incident.
I see far worse on 200 often, and not being sure what exactly the rules are with respect to pushing the enemy's buttons, it seems I am finding out the hard way by approaching the line to see if I stepped over it.
I'm thinking that maybe if enough people aren't happy with you and you start to push someone's buttons on 200, lots of people see it as a reason to express their dislike of you for previous events and they start reporting you. After some fixed number of reports within a fixed period of time, the result is an automatic 8 day mute.
Not sure that it's fair since others may be biased from prior events and are incorrectly reporting you for what appears to be a less than mute worthy interaction with one player on 200.
Learning the limits as I go, and bearing the resulting punishment, whether deserved imho or not.
I won't go into the specific details here and will let HTC respond to my email instead after they review the logs.
