> as you can see with e.g. Amazon reviews and fake news.

If Amazon wants to implement a stricter review check you can rest assured that it will be like YouTube demonitization all over again. So companies err on the safer side and take actions only when things get out of hand. Sure it is not perfect but it is better than system which leaves less leeway.

I read your below reply about how blockchain is required but you lost me at game theory, which frankly has become a go to explanation for everything blockchain. Why will this work in a blockchain? Is always followed by "because game theory and prisoners dilemma etc."

Still given that you are implementing such a system, I am curious what is your background and experience in game theory, maths, voting etc?
