GoNintendo does link to stories from other sites, but he never takes all the photos or the entire story/news from that site. He almost always limits it to one or two paragraphs and then includes a Link to go straight to the story.
I don't think that prevents people from going to my site...more likely it creates interest and more hits to my site.
This is really just how the internet works. Their is always going to be site linking your information. After all it is a WEB of information...all interconnected.
