Yes you do if you subscribe for notifications.

I still don't understand. Why?

The OP comment was: "It'd be cool if they added an option to subscribe for $10/year for a quick SMS and email notification if your account is compromised. I'd get it for myself and my family."

To enable this - you are giving your email, password, Payment details and Cell Phone number. The site as it stands today doesn't ask for any of this -- but if they were to take payments and do SMS notification they would.

If we decided to do notifications I would expect users to not re-use passwords from other sites. I would also expect that such a service would require a trusted security brand behind it to work.
