Comment Spam Defeat: Incoming
Google, Yahoo, MSN and many blog software vendors are promoting the rel=”nofollow” attribute for links. Nofollow will tell search engines that a link should not be given any pagerank(which is the only reason that comment spam exists). MovableType, for instance, just released a plugin that modifies all links entered in comments and trackbacks with the new attribute.
Dave’s right. I’m smiling. Not because I need comments on my blog turned on, but because I enjoy reading comments on other people’s blogs!
