One of the most alarming trends with fake news sites over the last year is that some of them have started mixing in articles about actual events with their hoaxes. I first saw this on long-time hoaxer Paul Horner’s site, News Examiner. As the above image shows, he’ll publish a fake story about Obama banning the Pledge of Allegiance right next to a real story about an Olympic athlete.
The reason for doing it is that some real news stories can of course bring in traffic. But more importantly, if someone sees a story on the site which they know is true, they may be more inclined to believe an utterly false one next to it. Mixing the true and the false just muddies the waters further, and may help convince people that a hoax site is credible. (Source)
