Many problems arise with Google's OpenID implementation (now deleted: accounts doubled, fake Google ID account, ...), asides with all the obvious privacy concerns (although quite opposed to security ones...)
Will it be possible to remove an account directly from the interface without involving the administrator team (yes, I do know they are very responsive)?
Some rules could apply:
- you can only delete recently created accounts (several days?)
- with reputation points under a certain limit (1?)
- Obviously only the account you are logged in (beware of XSS attacks!)
