After years of complaints, Meta has agreed to restrict the content teenagers can see on Facebook and Instagram. Evidence has continued to mount indicating that the company’s social media offerings are highly addictive and detrimental for youth in particular.

A bipartisan group of 42 attorneys general announced last October that they were filing a lawsuit against Meta due to the harmful effects of its products on teens. They say Meta has led some young people to develop eating disorders, body dysmorphia, and other mental health problems.

“Kids and teenagers are suffering from record levels of poor mental health and social media companies like Meta are to blame,” New York Attorney General Letitia James said in a statement announcing the lawsuits. “Meta has profited from children’s pain by intentionally designing its platforms with manipulative features that make children addicted to their platforms while lowering their self-esteem.”

In an effort to “give teens more age-appropriate experiences” on their apps, Meta representatives explained that they will be rolling out new protections over the next several months that prevent teens from seeing incendiary posts and stories “even if [they’re] shared by someone they follow.”

The guidelines will also automatically set those under the age of 18 to the most limited settings, so they will be unable to search for certain restricted topics or view anything that involves nudity.

However, critics point out that the protections are only relevant if teens accurately report their ages when signing up for new accounts.

“You do not need parental permission to sign up for a social media account,” Jean Twenge, a psychology professor at San Diego State University, told NPR. “You check a box saying that you’re 13, or you choose a different birth year and, boom, you’re on.”

In recognition of that reality, Meta says it is investing in age verification tools and technology to quickly ascertain when users are lying about their ages.
