Can you tell, when looking at a random web page, whether you should trust it? When scanning a page of reviews or search results, do you know which matches come from legitimate sources and which are scams? When reading a news feed, can you tell which items ought to be believed and which are slanted or manipulative? Can you detect propaganda or outright lies? Perhaps most importantly, what happens when you inevitably guess wrong while making some of these credibility assessments, and you unknowingly share falsehoods with your community, helping to make them viral? What if you are misled into making bad decisions for yourself and the people you care about, with potentially disastrous consequences?
The problem you write about has been in the center of my attention for almost 50 years. Your thinking is around creation of the truth verification authority. The problem is who will verify this authority, and then, who will verify those who will verify authority verifiers. And so on.
The recipient, be it a reader or a TV viewer is the only possible truth verifier. Sadly, in our reality, with media chasing an easy dollar not the truth, most people are so deeply, kindly speaking, misinformed that all sort of plain lies and fake news get a lot of traction. Your solution boils down to tell these people: you are stupid; we are wise, listen to us. Good luck with this approach.
The only productive approach is in an assumption that most people prefer to be wise than stupid. Some can make an extra effort cross that bridge, most need to be tricked into doing this. Consequently the correct approach is not in lecturing but in questioning, in tricking people to find on their own answers to their questions.
The hard work in this approach is in making sure that when seeking answers, people can have the truth as an option. Then, if it is done right, not all of them, but many enough to be significant will stand by the truth.
Lastly, the real challenge is to figure it out how to make profit when doing so, because this is the only way to make it sustainable; hence, successful. Obviously, I am writing to you because I figured it out how to make it work.
