I was a huge supporter of the silence penalty until Asmongold's video. The fact that's automated sets a disturbing precedent of censoring people simply because others don't like what you say. Automated systems do not belong in a punishment format by any means.
I hope this causes some changes. I'm not worried about being silenced myself because I'm overall not what I'd call a hostile person, but I don't really support any system that simply goes by "majority rules". It says that unpopular opinions that aren't aggressive or hateful can be silenced in WoW, and that's messed up.
Overall I'd say I'm...cautiously supportive of the system despite this. Maybe being called out on a system that is clearly automated will make them put at least a cursory amount of monitoring into it.
I still absolutely think Blizzard should have gone the route of supporting positive interaction instead of punishing negative interaction, though. LoL, FFXIV, and a myriad of other games all use a "thumbs up" or commendation system to tell a random player after playing with them that they were cool/nice/did a good job, etc, and I think it's a huge deterrent for assholery when you tie rewards to a system like that, and it also avoids stuff like this. Negative behavior would naturally go down because people simply have a reason to not treat players like shit.
