How do you control all the interactions between one person and the content ?
If you do it by the network, then it will be a privacy nightmare, all your interactions with the content could be monitored !

If not monitored, you can't enforce it's trustfulness and you are susceptible to Sybil attack, or fake behavior.

Do you maintain a double charge counter, one that can't be amplified by money and one that can ?
So that people who don't want to be exposed to money bias, can chose so.
