In the Australian pilot, users must first complete an online form on the e-safety commissioner’s website outlining their concerns. They will then be asked to send the pictures they are concerned about to themselves on Messenger while the e-safety commissioner’s office notifies Facebook of their submission. Once Facebook gets that notification, a community operations analyst will access the image and hash it to prevent future instances from being uploaded or shared.

They’re using the PhotoDNA algorithm already used with a shared database to blacklist images across several companies.
