I believe one of the hardest elements here is to battle with the incentives of those that publish such news. In effect a "crowd" based approach could help to distinguish signal from noise, that said, fake-new publishers will inevitably use bot-nets to counter act any crowd-based check.

Aside from human curation by a trusted group - which is extremely expensive - the only solution I can think of is a share-profit system to be implemented in already trusted news services and brands, so that more people can monetize their news articles. That way, you can use existing journalists to validate all news, and their brand to distribute, while providing incentives to niche-authors.

Any technological solution like the ones you are describing 1-3 can be attacked.

Thanks. Yes, the incentives should be based on building yourself a credible profile on the internet - like a trust button. A lot of community-based websites including Reddit, Jelly and others are moving in this direction but the challenge is how fast a community can move and how they can stop it in other networks such as facebook and whatsapp where this spread.
