The idea of the NoFollow attribute on links was to help prevent spam from appearing on user generated content sites, particularly Wikipedia. It was intended as a way to tell Google (and eventually all major search engines) that a link was not supposed to transfer any “link juice” to the recipient of the link. In essence, it was designed to stop SEO spammers from trying to insert their links where they didn’t belong for the sake of improved rankings.
