Hi Loren,

That's the security concern that prompted the confirmation step.
When you confirm your account for the first time, it associates an IP
address with your profile and stores a cookie on your browser. An
imposter would need to have access to one of those two credentials to
sign in as you (as Alok demonstrated).

The two-field requirement was originally so bots couldn't just throw
addresses against the login... they'd need to at least match up the
right name with the right address. That's probably not that hard,
and with the new measures it's no longer necessary, except as
security theater (two fields are more secure than one).

But if you were going to go to the trouble of impersonating someone
it'd be easier just to use e-mail itself. Programs like Apple Mail
put no restrictions on what you declare as a name or address for your
outgoing e-mail.
