Previously we used custom fields to denote a user was anonymous, this was risky in that custom fields are prone to race conditions and are not properly dedicated, missing constraints and so on. The new table `anonymous_users` is properly protected. There is only one possible shadow account per user, which is enforced using a constraint. Every anonymous user will have a unique row in the new table.
