Facebook is testing a new method to combat revenge porn in Australia, the Australia Broadcasting Corporation reports. The strategy entails uploading your nude photos or videos to Messenger in order to help Facebook tag it as non-consensual explicit media.

Facebook is doing this in partnership with Australian government agency e-Safety in order to try to prevent people from sharing intimate images without consent. If someone fears they are at risk of revenge porn, they can contact e-Safety. The organization might then tell them to send a nude photo of themselves to themselves via Messenger. Facebook’s hashing system would then be able to recognize those images in the future without needing to store them on its servers.
