Thanks for so much detailed answer. You came up with a hard system.
Probably not every user will decide to undergo a 100% verification (including biometrics, etc.) Someone will choose completely anonymity.
Of course, all at the discretion of the user, any user can remain anonymous.
The user's profile is a building material, on the basis of his data will work smart contracts and do filtering of advertising campaigns.
If the user is authorized through the face book his data public, but in our system he will be able to monetize them.
