Meta Study: Parental Controls Fail to Curb Teen Social Media Use
An internal Meta study called Project MYST, conducted with the University of Chicago and based on surveys of 1,000 teens and their parents, found that parental supervision and controls (time limits, restricted access, household rules) had little association with teens' attentiveness or ability to moderate social media use. The study also reported that teens experiencing adverse life events were more likely to show reduced attentiveness and problematic use. Those findings were disclosed during testimony in a Los Angeles County civil trial where the plaintiff alleges social media platforms — including Meta, YouTube, ByteDance (TikTok) and Snap — created addictive products that harmed children. Instagram head Adam Mosseri testified he was unfamiliar with the study, while Meta’s lawyers argued the research focused on perceived overuse rather than clinical addiction. The study has not been published publicly and no warnings were issued, according to testimony.
Internal Meta research revealing limited effectiveness of parental controls was introduced in high‑profile litigation alleging platform harms to minors; results could influence platform safety policies, legal liability, regulator scrutiny and advertiser trust.

Instagram's Teen Targeting Under Fire in Lawsuit
During testimony in K.G.M. v. Platforms et al. in Los Angeles County Superior Court, internal documents and emails showed Instagram tracked increasing time‑spent milestones and highlighted a focus on tweens and teens. The evidence cited daily usage rising from 40 minutes per day in 2023 to 46 minutes per day in 2026. The 19‑year‑old plaintiff (K.G.M., “Kaley”) alleges social media use contributed to addiction and mental‑health harm. Snap and TikTok settled before trial; Meta and YouTube executives, including Meta CEO Mark Zuckerberg, provided testimony. Plaintiff lawyers point to internal goals such as “total teen time spent” and emails noting age requirements were hard to enforce. Meta disputes causation and says it has implemented teen protections and age‑collection changes over time.
Zuckerberg Faces Court Over Teen Social Media Addiction
Meta CEO Mark Zuckerberg testified in Los Angeles Superior Court in a landmark trial examining whether social media products are addictive and harmful to teens. Plaintiff KGM (also known as Kaley), a 20-year-old, sued four social platforms; TikTok and Snap settled before trial while YouTube and Meta are defending. Trial evidence included Meta research saying parental supervision often could not prevent compulsive use and that traumatized teens were more likely to overuse social apps, a 2015 email chain showing Zuckerberg pushed to increase time spent by 12%, and internal estimates that millions of under‑13 children had Instagram accounts. The jury outcome could prompt legal reforms, settlements and platform changes.
Instagram Delayed Teen Safety Features Despite Early Warnings
A newly unsealed deposition from Instagram head Adam Mosseri, made public in a U.S. lawsuit alleging social apps are addictive and harmful to teens, revealed internal awareness at Meta of risks to minors and a lengthy delay in rolling out protections. Meta introduced an automatic blur for explicit images in Instagram DMs in April 2024, though the company had documented DM risks as early as 2018. The deposition cites a 2018 email chain including Meta security executive Guy Rosen and reports survey data that 19.2% of 13–15 year‑olds saw nudity or sexual images on Instagram they did not want to see; 8.4% had recently seen self‑harm content. Plaintiffs seek to hold platforms including Meta, Snap, TikTok and YouTube accountable for prioritizing engagement over teen safety.
