The mute was applied by a P Mod and was in place for 1 hour, there was no offence added to the account. The mute wasn't actually for the conversation you have shared, however in the interest of complete transparency I can say the actual evidence supplied for the mute was also incorrect.
My guess is you were doing something not chat related that caused some frustration or annoyance, and the P Mod saw 'red mist' and applied a mute. Just a guess of course, but does fit with what I can see.
In fairness the P Mod involved has a reporting accuracy of 98.3%, so that is a strong indicator that this was a one off reaction error.
I have reached out to the P Mod to seek their side of this, and depending how that goes I'll decide if any further steps are needed.
