I noticed this one as well. It is a nice feature, but I don't think I will use it much.

If the comments are good, I don't mind giving them credit (unless they use a spammy keyword as "Name"). If the comment is some kind of automated or manual spam attempt I move the comment to trash. I also don't think "great post. fake questions or fake general observation." adds much value, so I delete those as well (unless their from real people).
