You can add me to that list someone hacked my account like 3 weeks ago and changed the E-mail and password luckly I had many computers that still had me logged on to my profile and changed it back.
The point is these hacks need to stop its freaking annoying.
If their emails got changed, then I don't think this covers it. That's why I always thought it was fishy for AG to let you post your Yahoo email in since if a hacker hacked your AG and they know your Yahoo email due to your AG profile, not to mention you use a master password.
Here's a tip: If you can't keep track of multiple passwords for different accounts, then at least make sure your banking and email accounts all have different passwords then your average master password for the normal average site.
If they can't access their email they used for creating the account on AG, they will have a problem trying to verify they are the true owners of said account.
