In 2014 my friends and I made up something similar, and it went viral. Only the NYT and the Guardian called to fact-check, and when they couldn’t verify the story, didn’t run anything.
Everyone else ran it without even contacting us, even though our info was on the page. When your business model is based on impressions, fact-checking is an unnecessary expense. Ad revenue is what matters.
The funny thing is, the content farms masquerading as blogs don’t have as much power anymore because they have to pay just to have their stories seen. So it doesn’t seem to work as much anymore (based on a few more experiments we did).
