Just for reference, here's Alex Madrigal's submission list: http://news.ycombinator.com/submitted?id=alexismadrigal . Self-posts links to theatlantic every week or more.

http://news.ycombinator.com/user?id=nbj914 posts links to "outsideonline.com"

http://news.ycombinator.com/submitted?id=jnickhughes posts links (almost) only to soentrepreneurial.com.

I've seen others, but these were the easiest to find.

nhebb gives a great example of someone who has the same name as an Atlantic writer who appears to post only links to stories on the Atlantic written by them. (http://news.ycombinator.com/item?id=4108929)
