I think Social book mark is extension of social media. So it should know for webmaster that when submit link in social book marking site, always should be registered unique profile for a single website. It should follow the do-follow link. From my experience 10 do-follow social book marking sites would effect in our search engine ranking and even for high competition keyword .
