Everyone (except for players who'd pick Jhinpo, Ezreal or Lee Sin) who doesn't have an annoying summoner name gets the benifit of the doubt and doesn't instantly get fullmuted by me. But as soon as someone shows certain characteristics I mute them. For example, I had adc ping me back when I was pushing for level 2. Can you imagine? I had those goobers go outside of xp range after muting them so now I also have to farm as well... so annoying!
