Here's the problem:
When I limit comments only to registered users, my comment count drops off.
When i open up comments, and try to keep an eye on things, I find myself babysitting and moderating instead of writing my own posts.
I really don't want to END anonymous comments, because when you write a blog about local politics and media, sometimes folks have a very legitimate reason to remain anonymous.
But all it takes it one or two people who are determined to aggressively confront anyone who dares disagree with them (you know the type) and then you have readers refusing to come back because their feelings are hurt.
What I am wanting is some way to allow readers to block certain commenters. It would be the way some chat rooms work. Under a comment, there could be a "block commenter" button, and then that reader wouldn't have to put up with this particular commenter anymore.
I went through all the plugins in the here and found nothing like that.
I have a feeling this would be a very popular plugin.
