I don't get it...
Why would anyone use their real name and address on a site like this? And, conversely, surely the email addresses *are* real, or AM couldn't send notifications/whatever to members?
The only personally identifiable data would be a name on a credit card, which is hardly unique, and possibly the last 4 digits of the CC number, which seems to be in the database. So, on the face of it, the database seems close to useless, unless you can match a name on a CC with an email address.
