>>I think you have a misconception of what the word "fake" means - so until you figure that out this is all pointless.

We're talking about "fake news", not "fake". Are you trying to be a reporter again? ;-) Try this: https://en.wikipedia.org/wiki/Fake_news

Claire Wardle of First Draft News identifies seven types of fake news:

satire or parody ("no intention to cause harm but has potential to fool")
false connection ("when headlines, visuals or captions don't support the content")
misleading content ("misleading use of information to frame an issue or an individual")
false content ("when genuine content is shared with false contextual information")
imposter content ("when genuine sources are impersonated" with false, made-up sources)
manipulated content ("when genuine information or imagery is manipulated to deceive", as with a "doctored" photo)
fabricated content ("new content is 100% false, designed to deceive and do harm")\

Why focus only on the last type? The one I'm seeing most often is false content.

The International Federation of Library Associations and Institutions (IFLA) published a summary in diagram form to assist people in recognizing fake news. These points have been corroborated by experts in the cognitive science of information processing. Its main points are:

Consider the source (to understand its mission and purpose)
Read beyond the headline (to understand the whole story)
Check the authors (to see if they are real and credible)
Assess the supporting sources (to ensure they support the claims)
Check the date of publication (to see if the story is relevant and up to date)
Ask if it is a joke (to determine if it is meant to be satire)
Review your own biases (to see if they are affecting your judgement)
Ask experts (to get confirmation from independent people with knowledge).
