Digg Deprives Spammers Of Link Juice, Goes Nofollow

In a move to keep spammers at bay, popular social bookmarking site Digg has added a "rel=nofollow" tag to all links on the site that it does not consider trustworthy. Comments, less popular posts and links on user profiles would not derive link juice. Though in its blog, Digg was not specific as to what levels of popularity would get the Nofollow tag removed.

A number of people submit stories to Digg just to garner links in hope to get a rush of traffic. Even if the link does not gain in popularity, search engine crawlers count them in and return value to the spammers.

As per Digg, it was contemplating this move since at least 2007 and the decision was taken in consultation with leading SEO/SEM experts. But as Google had forced Twitter to integrate Nofollow, experts believe that Google could well have something to do with the move.
