Digg Adds No-Follow to Combat Spam
“These changes reduce the incentive to post spammy content (or link spam) to Digg, while still flowing ’search engine juice’ freely to quality content. We’ve added rel=”nofollow” to any external link that we’re not sure we can vouch for. This includes all external links from comments, user profiles and story pages below a certain threshold of popularity.”
