It would be great to generate a brand new random email address for every service with which a user signs up. However this would only work if a user is able to reactivate the temporary email address to do password recovery. Otherwise we would need to prevent password loss by reusing passwords, not good.
It would be easy to rediscover which temporary email was used for a service and reactivate it by searching an inbox for the service's "email address verification email" and reading the "to address".
