A class-action lawsuit filed in an Australian court alleges that Facebook and Instagram exposed young users to harmful material while using engagement-driven algorithms to keep them online.
The case claims Meta’s systems may have amplified content that could damage children’s mental health and well-being.
Plaintiffs allege the platforms were designed to encourage prolonged use, potentially making it difficult for young users to disengage.
The lawsuit could intensify scrutiny of Meta’s safeguards, recommendation systems and age-verification practices.
It also adds to a growing wave of legal action worldwide examining whether social media companies adequately protect children from online risks.
Meta has faced similar criticism in other jurisdictions, but the Australian proceedings could test the company’s responsibilities under the country’s consumer and child-safety laws.
The allegations have not been proven in court, and Meta will have an opportunity to respond as the case proceeds.
