Not really, the way voting works the main two groups are all public people, and the third group is all the voters and holders of EXP. Those might be anonymous for the most part, but not fake as they all must hold EXP to vote. Snapshots will be used.
That's a very interesting idea. It would be most effective if people couldnt create new identities. We cant stop that very easily, however we could limit identities that gain socialnet features like basic income. So if you earn a bad reputation you will be booted from basic income.
