There seem to be centralised approaches to combating fake news, such as Youtube suppressing fake news about coronavirus. Are there any decentralised approaches though? When most people share a news article, they don't first check it with one of the fact checking agencies. Are there some socially accepted approaches to factchecking?
Motivation: Maybe I just suck at communicating but responding to posts that seem to be factually wrong is not always appreciated. In a science lab people might talk relatively impartially about facts but in many other parts of life emotions rule and whether statements are true or not is irrelevant. On the other hand relying just on centralised fact-checkers and main-stream news being diligent seems like an insufficient approach, and a fragile one. Vendors of fake news can use micro-targeting to inject divisive messages into small niches. How can society be resilient to this? I would have thought that objective reality is almost by definition a good place to start building common ground, but then I am a scientist.
Note: I realise that fake news is not just about politics but lot of it is, so I guess you folks are probably best placed to answer.

Micro-targeting: The best summary I read was by a masters student; I can ask her whether she would be happy to publish it, if there is interest.
