In Asti, northern Italy, Rossella’s death has moved from private grief into public litigation.
The 12-year-old died by suicide after what her parents describe as months of increasing exposure to depressive and self-harm-related content on social media. The case took a decisive turn only after her death, when her family accessed her devices and discovered what they describe as a hidden online identity, including a secret Instagram account named “Just a dead pers0n”.
For her parents, the discovery reframed everything. What once appeared as an emotional struggle is now being examined in court as a possible consequence of algorithmically reinforced exposure.
The allegation: when recommendation systems reinforce distress
At the centre of the lawsuit filed by Rossella’s parents, alongside other Italian families, is a direct challenge to Meta and TikTok.
The families allege that once the child began engaging with depressive content, platform recommendation systems amplified similar material, creating a reinforcing loop that intensified exposure rather than interrupting it.
According to their account, Rossella began searching for depressive content in September 2023. They say the algorithm repeatedly pushed similar material over the following months, deepening her immersion in it.
Five months later, she was dead.
The case now tests a fundamental question: whether algorithmic systems can be treated as neutral tools, or whether they function as active participants in shaping outcomes.
Meta and TikTok deny the claims
Both companies have strongly rejected the allegations.
Meta says it provides Teen Accounts, moderation tools, and safety systems designed to limit exposure to harmful content for minors. It argues that adolescent mental health is influenced by multiple factors, including offline environments and parental involvement.
TikTok says it removes over 99 percent of violating content and continues to invest in systems that diversify recommendations, block harmful searches, and connect users with support resources.
Both companies maintain that responsibility cannot be attributed to platform design alone.
A wider regulatory shift already underway
The Italian case is unfolding at a time when governments are tightening their approach to platform regulation.
The United Kingdom has announced plans to restrict social media access for children under 16, marking a shift towards stricter age-based controls.
In the United States, courts have already found major tech companies negligent in aspects of platform design linked to harm among young users.
Within the European Union, enforcement of the Digital Services Act is intensifying, with regulators demanding stronger safeguards and accountability for how platforms recommend content.
The direction is increasingly clear: algorithmic systems are no longer being treated as passive infrastructure.
Parents caught in a system they cannot fully control
Families involved in the Italian lawsuit argue that existing safeguards are not enough.
They say children can easily bypass restrictions through alternative accounts, device switching, or widely available online tutorials.
For many parents, the issue is not awareness but practicality. Monitoring usage has become an exhausting, near-impossible responsibility.
Several accounts also point to behavioural shifts observed at home, including reduced attention spans and a gradual replacement of reading habits with continuous scrolling.
The science debate: addiction models and unanswered questions
The World Health Organization has warned about rising problematic social media use among adolescents, linking it to sleep disruption, reduced wellbeing, and broader developmental risks.
Research published in journals such as JAMA Pediatrics has identified neurological differences among heavy users, particularly teenagers whose brains are still developing.
Experts supporting the Italian case argue that platform design mirrors behavioural reinforcement systems similar to gambling, where likes and notifications trigger dopamine-driven engagement loops that encourage prolonged use.
However, other psychologists caution against drawing direct causal conclusions. They argue adolescent mental health is shaped by multiple overlapping influences and warn that excessive control may itself be counterproductive, emphasising trust over surveillance.
A case that forces a larger question
For Rossella’s mother, the lawsuit is not only about assigning blame, but about recognition.
She says the risks were not visible to her until it was too late, and that speaking out is an attempt to ensure other families are not left in the same position.
What began as a private tragedy has now evolved into a structural challenge, one that sits at the intersection of technology, law, and childhood development.
The question the court cannot avoid
As courts, regulators, and companies enter this dispute, the issue extends beyond one platform or one case.
It is now about design, responsibility, and exposure.
Because in an era where algorithms decide what children see next, the question is no longer just what they are shown—but who is accountable for what it does to them.
