CNN – Meta is taking steps to crack down on the spread of “revenge porn” images of teenagers on Facebook and Instagram.

A new tool, called Take It Down, takes aim at a practice where someone posts an explicit picture of an individual without their consent to publicly embarrass them. Revenge porn has skyrocketed in the last few years on social media, particularly among young boys, according to the National Center for Missing and Exploited Children.

Take It Down, which is operated and run by NCMEC, will allow minors for the first time to anonymously attach a hash – or digital fingerprint – to intimate images or videos directly from their own devices, without having to upload them to the new platform. To create a hash of an explicit image, a teen can visit the website TakeItDown.NCMEC.org to install software onto their device. The anonymized number, not the image, will then be stored in a database linked to Meta so that if the photo is ever posted to Facebook or Instagram, it will be matched against the original, reviewed and potentially removed.
