Of the last several months of gameplay, not once have I seen someone who was actually at fault get a mute or any other punishment. However, several times I have seen perfectly within-the-rules become muted because someone didn’t like them. It seems you don’t even screen abuse reports, it’s like you just automatically get muted if someone reports you, and this can only be good for trolls, people who don’t play for the game itself.
Honestly, if you don’t check the reports and make sure a rule was actually broken, why do you have the report system in place?
