I think this is a horrible idea.

Just imagine how many times we have been wrong in our judgement of the behaviour of citizens. What would the social credit score of Ghandi or Martin Luther Kind have been, at the time of their prominent actions?

We have proven time and time again that there is no sure way to judge how "social and acceptable" something is, and the value of a behaviour to our society.

What is seen as "unsocial" today may be applauded by historians in the future.
