All these report systems regarding "toxic" members in games are faulty at their core, we have a /ignore system already in wow, we only need something like this for spam advertisement but it would still need to be more advanced than a simple mass report( spamfilters etc).
Shit like this piss me off massively as instead of focusing on improving the game they implement some faulty f ucking crybaby system where mass reporting is the name of the game and u can basicly control anyones chance to communicate. The rules are so vast covering that you could also get banned/silenced "legit" per the TOS due to it covering everything under the sun, when in reality some idiot just made a terrible play and u call him a f ucking idiot rightly so.
Stuff like this should be for offenders who whisper spams a certain individual for an extended time, making new chars just to continue abuse, to prevent harrasment, and should be under gamemaster review.
There is already a mature language filter ingame that is turned on by default when you start out, like f u ck off with this silencing bullshit.
But then again focus is purely on making the game as casual as possible and when blizzard implements something like this they can get an article spot in some claim to be PC magazine with praise of "dealing with trolls" when they system is utter shit and abuseable.
