Facebook's privacy regulations have made legitimate strides over the course of the social network's lifespan, and the company's new 'profile picture guard' is a move to protect the last bit of vulnerable personal identification on people's accounts. The optional feature puts a digital block on users' profile pictures, preventing anyone else from being able to save the picture or even take a screenshot.
Up until now, Facebook users have been able to make every single aspect of their profiles private save for their profile pictures. This meant that sketchy third parties had the ability to use the effectively publicly available pictures for anything, from catfishing scams to the questionable "hot singles near you"-style ads.
Profile picture guard was created specifically for women in India, and it was developed in partnership with NGOs like the Centre for Social Research, Learning Links Foundation, Breakthrough, and Youth Ki Awaaz.
