Facebook acknowledged there was a glitch in the system, which allowed users to access off-limit photos of other users, but claimed that only a limited number of users were affected. Facebook did not disclose how many people were affected.
Many users have their Facebook profile locked down. Only profile picture data is often available to display on some profiles. Users who took advantage of this flaw were able to ‘report’ a profile picture as ‘nudity or pornography’, which then led to the ‘reporting’ tool to display the images.
However, images of Facebook chief executive and founder Mark Zuckerberg were uploaded to image-sharing sites after his own profile was exploited.
