Facebook leaked data all over internet--including non-users

Security researchers who revealed Facebook's shadow profiles vulnerability are claiming that Facebook leaked massive amounts of data, including private phone numbers and other personal data--despite what Facebook told its users.

Facebook had announced the fix of a bug that inadvertently exposed the private information of over six million Facebook users. In addition, Facebook apparently is collected non-user phone numbers and email addresses and then matched the data to people. Here is the technical explanation of how data gets merged over several sets of databases, and unique links are discovered.

Knowing the information industry, I expect that this data will be for sale very shortly.
