Facebook is ramping up its efforts to combat the spread of non-consensual “revenge porn” images across its main website, Instagram and Messenger, it confirmed this week.

The move expands on a pilot scheme announced last year that asked any users who were concerned about the spread of intimate images to proactively upload them using the encrypted Messenger service, where photo-matching technology could prevent further sharing. The social network has stressed it does not store the images long term, but instead keeps their unique fingerprint, or “hash.”
