Targeting Children: How Meta's Ad Platform Enables Marketing to Minors

Meta prohibits users under 13 from creating accounts and restricts advertising targeting for users aged 13-17. But these policies are undermined by ineffective age verification — children routinely create accounts with false birth dates — and by targeting mechanisms that allow advertisers to reach teenagers with products and messages that regulatory frameworks consider inappropriate for minors. The result is a platform where millions of children and teenagers are exposed to advertising for gambling, alcohol, weight loss products, and other age-inappropriate categories through gaps in Meta's enforcement.

The Age Verification Failure

Meta relies on self-reported birth dates for age verification, a mechanism that every teenager knows how to circumvent. Surveys indicate that a significant percentage of children under 13 have Facebook or Instagram accounts created with false birth dates. Meta has access to numerous signals that could identify underage users — device sharing patterns, communication patterns, content preferences, writing style — but implementing robust age detection would reduce its user count and advertising reach. The financial incentive to maintain a large underage user base conflicts directly with the regulatory obligation to protect minors.

Advertising to Teens

For users identified as 13-17, Meta restricts but does not eliminate targeted advertising. Advertisers cannot target teens based on interests or activity, but can target by age, gender, and location — enough to direct age-inappropriate advertising to teenage audiences. Gambling companies, cryptocurrency platforms, weight loss products, and other advertisers whose products are restricted for minors have been documented reaching teenage audiences on Meta's platforms through a combination of broad targeting and inadequate enforcement.

The psychological impact of advertising on developing minds is well-documented. Teenagers are more susceptible to social comparison, peer pressure, and emotional manipulation — the same dynamics that Meta's advertising platform is optimized to exploit. Targeted advertising that leverages these vulnerabilities in minor users raises ethical questions that Meta's current policies do not adequately address.

Parents should assume that age restrictions on social media platforms are ineffective and implement device-level controls. Legislators should mandate meaningful age verification rather than relying on self-reporting, establish clear liability for platforms that fail to prevent advertising to minors, and require transparency about the age demographics of advertising audiences.
