This would certainly have upfront advantages, like increasing the amount of information deemed "credible". However, there's a problem: how do you trust an actor controlling a system like that?

i.e. - If I wanted the power to discredit almost anything online, I would propose such a system because it can only serve its purpose under the operation of a private entity. It wouldn't function properly on an open platform because that information would evidently be just as non-credible.

I'd make sure the system allows full transparency on how the metric is formed - for instance it shows that vactruth.com has a low reliability weighting, but a high verifiability weighting; but that the Journal of Comparitive Neuroscience has a high reliability score but a low verifiability score (it costs about US$32,000 a year for a 24 issue subscription).

I'd then let people tweak their own metrics and have the ability to share them with others.
