It won't stop the army of fact-checkers debunking articles for having no reliable sources, and denouncing them on social media. Social being both the main distribution for fake news, and also the platform where articles are routinely ridiculed and mocked. Something like Wales' WikiTribune[1] are a response to fake news and propagandists, and are a welcome step to try and address the issue. Facebook are also up in arms about this and are trying to spot fake news either algorithmically or using a paid taskforce of highly trained fact checkers (the mechanical turk approach). Reddit also warns users of posts which are regarded as fake news and warns users to take them with a pinch of salt.
