"Anger mounts after Facebook's 'shadow profiles' leak in bug"
"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.
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 invisible collected information is then being stored in each user's 'shadow profile' that is somehow attached to accounts."
