Correct me if I'm wrong, but I thought there was some functionality at some point wherein: - A muted person could not comment on a post from the person who had muted them. - A non-muted person could shout-out that muted person. - The muted person could respond to anything in the hierarchy tree underneath the shout-out. It was sort of like being a vampire - once you invite them in, there's nothing you can do. I thought that was pretty cool. As far as the feeds, I've always thought it was a little weird that ignored users don't show up in global feeds. That's kind of the point of "global feeds" - to see the stuff that isn't specific to you. As far as "hush" I think it's pretty subtle. You want to make it obvious what it's doing, screen that text back.
