Fake news is fake news
There's no such thing as fake news it's just "paid-for" advertising or indeed someone's opinion that is presented to look like news. Verify the source - recording the details of legit news sources can't be that onerous. Present an advert so that it looks like an advert and doesn't masquerade as something else.
The content is irrelevant, but if Facebook's advertising actually looked like adverts no one would use Facebook. You only know it's an advert once you start to interact with the content - by clicking the three dots in the top right and select "hide ad". Until that point it looks like anything else in your newsfeed.
There should be laws to distinguish advertisements clearly and then at least half the problem goes away. Or, maybe if people were more persistent in flagging everything that appears in their newsfeed that they didn't ask for as "spam" then that might send a strong message too.
