The problem is and always will be that truth is tricky to define, and “blocking fake news” is immensely easy to exploit for nefarious purposes. Perhaps the better solution here is not to try to block the flood but to manipulate it by using market incentives. Notice how high-quality journalism tends (again, quite subjective) towards subscriptions and sponsorships, as users will actively want to participate whereas lower-effort content has to lean heavily on black-box advertising networks. This could be solved with a few changes: tax advertising a lot more, and use these funds to subsidise subscriptions and sponsorships in media.
