The definition of a fake news web site is, basically, selling garbage content for profit.

“If the standard for traditional journalism was to ask, “Is this verified?,” the standard for new digital publications like Buzzfeed is to ask, “Is this clickworthy?” The answer to that second question for everything Buzzfeed produces is, “Yass!””

Fake news is almost always about the profit opportunity. Long ago, this blog documented the production of social media propaganda posters for the purpose of selling eyeballs to advertisers. 2016 saw an explosive growth of online, for profit, social media-based fake news services.
