https://www.mylife.com How about US and Western social scoring?

A decentralized social score is already used universally to check against people in many countries. Rating information no matter how decentralized you make it all gets collated into a centralized service eventually, or the product you are creating gets more centralized over time. Everything historically centralizes over time.

There's already websites and companies that already do this. The data is decentralized, in that they pull this data from many different sources and piece it together. It is then centralized. They rate you as a person, your income, your education, and many things.

Anyone who creates a scoring system is to be viewed with extreme suspicion, theres really no good reason to do this because it WILL be abused by people further down the road. I already gave you one example of MyLife, that is just in it's infancy stages and allows pretty much anyone to spy on anyone else for a nominal fee.

Just don't do it, let things be. By making more scoring things you will be feeding into things like this. Someone will take what you did and connect it with other things and centralize it, things will be done with that data that you couldn't possibly have predicted. Therefore it is better logically to just not do it at all, working to further make things anonymous however is a good endeavor.
