It will be interesting to see how Facebook's plan to test a system of fact checking news stories works out. They are planning to add warning labels to disputed stories, you can click on the label to see why it is disputed.
Ideally this will show how fake the mainstream news is. If they don't label the news fairly, hopefully it will create a sufficient debate to wake up people to the problem of bias. Maybe the 3rd party fact checkers will get educated too.
Interestingly, the recent story about a boy dying in a Santa's arms was originally posted as true, then it was thought a hoax, then it was verified as true. Good luck with that Facebook. They are going to be surprised how often this happens.
What about stories based on "unnamed sources"? On what basis will they judge them?
I also wonder how will they treat news on paranormal phenomena?
And people will start testing their methods with stories, real and fake, designed to show flaws in the system.

In the announcement, Facebook confirmed that it will be working alongside organizations that are signatories of “Poynter’s International Fact Checking Code of Principles.”
Business Insider reports that these organisations will include the likes of Snopes, ABC, Politifact, and FactCheck.org, all of which have records of left-wing partisanship — particularly throughout the 2016 election.
They have been suppressing fake news for some time already:

Historically, we have relied on our community to help us understand what is fake and what is not. Anyone on Facebook can report any link as false, and we use signals from those reports along with a number of others -- like people sharing links to myth-busting sites such as Snopes -- to understand which stories we can confidently classify as misinformation. Similar to clickbait, spam and scams, we penalize this content in News Feed so it's much less likely to spread.
