I wonder how things would go if the score was private.

Also, what would be the consequences of knowing who upvoted you or downvoted you ? Now that I think about it, neither imgur or hn let you see that. Should we be entitled to that kind of data ?

Punishing people based on public consensus is lynching.

Sorry, there is a misunderstanding. It's the other way around. I believe the black mirror system is more efficient to establish social control and is more perverse because everyone is policing it, watching you and reporting you. It's the real nature of big brother (what I remember from the book): everyone is big brother in the end and there's no escape.

Our life would be worse in a black mirror system than in a Chinese system.

Both systems are fucked up though.
