Hello Christina,
I appreciate your comment but I stand by my statement. I think it's a thought worth exploring. Why are comments by semi-autonomous community members any better or worse than someone employed by the site who is autonomous as well. Isn't anonymity and the ability to say what you want exactly what leads to such written abuse? The reviewers are, at the very least, semi-autonomous. What's to keep those reviewers fair and honest in their comments? Nothing really as I see it. So are we solving problems are creating more ? I don't see how adding another gate to the door is any better than what you already have.    btw for the record...I do not practice spam or any of the other methods of responding to comments that you mention in your first sentence.
