Why You Should Nofollow Your Blog Comments?
- You get increased automated comment spam
- You get increased spam from outsourced commenting
- You get increased spam from people using commenting efficiency tools (Comment Kahuna, Comment Hut etc)
- You get increased spam from people using dofollow search engines
- You get increased spam from people using lists of dofollow blogs
- You get Internet Marketing Gurus encouraging their interns to comment on their behalf
