User blog comment:The Completionist/What function does the ignore list have, and does anybody actually use the mute button?/@comment-5263329-20130930164854/@comment-23886783-20130930235913

but that isn't the mute button's fault, right? If the player is that sort of person, then they're going to be a drag on their team regardless. That I'm-always-right-I-don't-need-advice smug attitude you mentioned may even lead his teamates to mute them first, depending on whether he types back or stays silent.

So, you know...still works out, sort of. At that point, it's a question of whether reporting for being a lousy teamate works or not ;)
