I think that a better way to combat viral Fake News is to provide additional information in real-time to users so they have the full story, rather than biased and/or inaccurate (contradicted by additional facts). Boolean by GainingSteem.Com is doing just that. No censorship EVER, but instead, additional information so people have all relevant facts when consuming news.
