Meta-funded online tool lets people remove their explicit images from the internet

“Once you send that photo, you can’t take it back,” goes the warning to teenagers, often ignoring the reality that many teens send explicit images of themselves under duress, or without understanding the consequences.

A new online tool aims to give some control back to teens, or people who were once teens, and take down explicit images and videos of themselves from the internet.

Called Take It Down, the tool is operated by the National Center for Missing and Exploited Children, and funded in part by Meta Platforms, the owner of Facebook and Instagram.

The site lets anyone anonymously – and without uploading any actual images – create what is essentially a digital fingerprint of the image. This fingerprint (a unique set of numbers called a “hash”) then goes into a database and the tech companies that have agreed to participate in the project remove the images from their services.

Now, the caveats. The participating platforms are, as of Monday, Meta’s Facebook and Instagram, Yubo, OnlyFans and Pornhub, owned by Mindgeek. If the image is on another site, or if it is sent in an encrypted platform such as WhatsApp, it will not be taken down.

In addition, if someone alters the original image – for instance, cropping it, adding an emoji or turning it into a meme – it becomes a new image and thus need a new hash. Images that are visually similar – such as the same photo with and without an Instagram filter, will have similar hashes, differing in just one character.

“Take It Down is made specifically for people who have an image that they have reason to believe is already out on the web somewhere, or that it could be,” said Gavin Portnoy, a spokesperson for the NCMEC. “You’re a teen and you’re dating someone and you share the image. Or
