As far as I am concerned, no one in the right frame of mind would use something like this, or like hivemail, or any other website provided mail client as their primary email solution.

This is designed to simply add another layer of privacy to your existing mail, with the flexibility to change alias whenever you want. An example to use this system, would be to setup an alias, use it for a subscription to another site. Once you start getting bombarded with spam, you just change alias. Using your real email in that case would live you vulnerable to spams.
