What are your thoughts on "Soft" Comment Spam. The kind of comment spam from people who manage websites. They're generally related to your post but their "Names" are quite keyword rich. I've noticed a few who used to spam my blog appearing on some of the top commenters lists on my feed reader, so I wonder if I was just being harsh. I just hate the fact that usually their e-mail address was firstname.lastname@example.org, or they commented under different aliases. Your thoughts?
