As far as I understand it, the identity verification is voluntary, meaning only people who want to do it will do it. People who get verified will have higher reputations, be able to vote in referendum, and will have higher rewards. But for people who want to remain anonymous, they can, their rewards will be lower however....this was the solution to robot accounts and the problem of people owning lots of accounts....I think no solution is perfect, but having it voluntary should be a good thing I think.
