Meta details 'adult classifier' tool for catching teens who lie about their age on Instagram

Meta has shared more information about how it plans to use AI to catch teens who lie about their age on Instagram. As first reported by Bloomberg, early next year, the company will deploy “adult classifier,” a tool it says will identify users who are younger than 18 and automatically apply Instagram’s more restrictive privacy settings to them.

According to Allison Hartnett, Meta’s director of product management for youth and social impact, the software will look at indicators like the accounts a user follows and the content they interact with regularly. If the tool suspects someone is under 18, it will move them to a teen account, regardless of what age they claim to be on their profile.

Meta did not immediately respond to Engadget's request for comment.

Meta first said it would use AI to identify young users who had lied about their age when it began rolling out teen accounts in September. With those accounts, the company automatically applies Instagram’s most stringent privacy settings to kids younger than 16. For instance, the accounts are automatically set to private, and they can’t message strangers. Facing pressure from lawmakers and parents, Meta had already been applying many of those restrictions to underage users before the rollout of teen accounts, but with the official launch of the feature, the company made it so that teens cannot change those settings without approval from a parent.

On Monday, the company didn’t disclose how accurate the adult classifier tool is at determining a person’s age. Meta told Bloomberg it would eventually give people who are wrongly identified by the software the ability to appeal, though the social media giant is still working out what that process will look like.

The company will prompt teens who attempt to manually change the age listed on their account to prove their identity. Users will have the option of either uploading an official government-issued ID or sharing a video selfie to Yoti. Meta previously partnered with Yoti to bring age verification to Facebook dating. The company’s machine learning algorithm estimates a person’s age based on their facial features. Once Yoti shares its estimate with Meta, they both delete the video.

The adult classifier software is part of broader effort by Meta to make it more difficult for people to lie about their age on Instagram. Separately, the company plans to flag teens who attempt to create a new account using an email address that’s already associated with an existing account and a different birthday. It also plans to use device IDs to get a better picture of who is creating a new profile.

Meta, alongside Google and TikTok owner ByteDance, recently failed to convince a US federal judge to dismiss a series of lawsuits alleging the companies failed to adequately protect their young users from the harmful and addictive effects of social media use.
