Anger mounts after Facebook's 'shadow profiles' leak in bug [View all]
The personal information leaked by the bug is information that had not been given to Facebook by the users - it is data Facebook has been compiling on its users behind closed doors, without their consent.
A growing number of Facebook users are furious and demand to know who saw private information they had expressly not given to Facebook.
Facebook was accidentally combining user's shadow profiles with their Facebook profiles and spitting the merged information out in one big clump to people they 'had some connection to' who downloaded an archive of their account with Facebook's Download Your Information (DYI) tool.
According to the admissions in its blog, posted late Friday afternoon, Facebook appears to be obtaining users' offsite email address and phone numbers and attempting to match them to other accounts. It appears that the covertly collected information is then being stored in each Facebook user's invisible 'shadow profile' that is somehow attached to accounts.

You can opt out of being on FB - harder to opt out of having your data collected by the NSA and such.
