I don't think I have anybody muted, but I think I have been muted (or filtered... something) because I made a shit post just to see what would happen. Very unHubski like I know, but again, I think everybody has done that at least once or twice. No worries I've learned from the mistake and dealt with it. I think muting as a whole, can be useful only if you're dealing with spammers. Muting somebody just because and I quote from the post which I recently deleted "a total authoritarian asshole" because you implied that a person who didn't take a course of action should suffer the same punishment as someone who follows through on a course of action. Anyway apparently if you think that somebody who makes a tasteless joke about terrorism, should suffer the same consequences as a terrorist, you're worth muting. God forbid I say something that pisses people off, eh I think it's a fact of my life. Anyway I think I'll cut down on voicing my opinions since people find them too radical or "authoritarian" for this site. For the record I was also compared to Joseph Stalin from post, from somebody I've never had any interaction with...
EDIT: apparently OP has me hushed. this is interesting.
