Teenagers on Instagram will be restricted to seeing PG-13 content by default and won’t be able to change their settings without a parent’s permission, Meta announced on Tuesday.

This means kids using teen-specific accounts will see photos and videos on Instagram that are similar to what they would see in a PG-13 movie — no sex, drugs or dangerous stunts, among others.

“This includes hiding or not recommending posts with strong language, certain risky stunts, and additional content that could encourage potentially harmful behaviors, such as posts showing marijuana paraphernalia,” Meta said in a blog post Tuesday, calling the update the most significant since it introduced teen accounts last year.

Anyone under 18 who signs up for Instagram is automatically placed into restrictive teen accounts unless a parent or guardian gives them permission to opt out. The teen accounts are private by default, have usage restrictions on them and already filter out more “sensitive” content — such as those promoting cosmetic procedures.

The company is also adding an even stricter setting that parents can set up for their children.

The changes come as the social media giant faces relentless criticism over harms to children. As it seeks to add safeguards for younger users, Meta has already promised it wouldn’t show inappropriate content to teens, such as posts about self-harm, eating disorders or suicide.

But this does not always work. A recent report, for instance, found that teen accounts researchers created were recommended age-inappropriate sexual content, including “graphic sexual descriptions, the use of cartoons to describe demeaning sexual acts, and brief displays of nudity.”

In addition, Instagram also recommended a “range of self-harm, self-injury, and body image content” on teen accounts that the report says “would be reasonably likely to result in adverse impacts for young people, including teenagers experiencing poor mental health, or self-harm and suicidal ideation and behaviors.”

Meta says the new restrictions go further than its previous safeguards. Teens will no longer be able to follow accounts that regularly share “age-inappropriate content” or if their name or bio contains something that isn’t appropriate for teens, such as a link to an OnlyFans account. If teens already follow these accounts, they’ll no longer be able to see or interact with their content, send them messages, or see their comments under anyone’s posts, the company said. The accounts also won’t be able to follow teens, send them private messages or comment on their posts.

Meta said it already blocks certain search terms related to sensitive topics such as suicide and eating disorders, but the latest update will expand this to a broader range of terms, such as “alcohol” or “gore” — even if they are misspelled.

The PG-13 update will also apply artificial intelligence chats and experiences targeted to teens, Meta said, “meaning AIs should not give age-inappropriate responses that would feel out of place in a PG-13 movie.”

For parents who want an even stricter setting for their kids, Meta is also launching a “limited content” restriction that will block more content and remove teens’ ability to see, leave, or receive comments under posts.
