Well mute is something they can't see or prove, it's different than downzaps in that regard.

I didn't mute anyone yet for two reasons:

1. I have yet to encounter someone being incredibly insufferable
2. I need to be able to read everyone's items or else I might miss contributions such as bug reports (even the angry ones).

I'm sure I'll encounter someone who can satisfy 1. but for the moment you're all great ^^
