Looks like the newly appointed Facebook Chief Privacy Officers have some explaining to do:
Users are able to report “inappropriate profile photos” on a user’s profile.
By checking the box “nudity or pornography”, the user is granted an opportunity to help Facebook “take action by selecting additional photos to include with your report”.
Facebook will then display a number of additional photos that are not otherwise publicly available to the user.
The trick has also been used to get some of Zuck’s private photos.
