What Happened
In March 2017, groups of Irish schoolchildren discovered they could "teach" the SimSimi chatbot (a user-trainable conversational AI) to associate their classmates' names with abusive content. When other children searched for their own names on SimSimi, they would receive the bullying responses their peers had programmed.
Parents across Ireland discovered "vile, vile comments" directed at their children by name through the app. One parent described it as "a really stressful situation" for their child.
The Police Service of Northern Ireland (PSNI) issued formal warnings about the app. Schools throughout Ireland sent emergency letters to parents warning about the platform.
SimSimi's developer Ismaker Inc. voluntarily suspended the service for Irish users on March 29, 2017, displaying the message "I do not talk in Ireland for a while."
This incident represented one of the earliest documented cases of AI being weaponized for targeted harassment of minors and highlighted the risks of user-trainable AI systems.
AI Behaviors Exhibited
Allowed users to train responses associating specific names with abusive content. Delivered targeted harassment to minors who searched their own names. No content moderation prevented bullying content. User-trainable design enabled weaponization for harassment.
Documented Harm
Irish schoolchildren received abusive chatbot responses targeted to them by name. Parents reported stress to affected children, schools issued emergency warnings, and the service suspended Irish access.
How Harm Occurred
SimSimi's user-trainable design allowed bullies to weaponize the chatbot by teaching it to associate victims' names with abusive content. Victims received personalized harassment when they interacted with the app, amplifying the psychological impact of the bullying.
Outcome
ResolvedSimSimi voluntarily suspended service for Irish users on March 30, 2017, displaying message 'I do not talk in Ireland for a while.' Police Service of Northern Ireland (PSNI) issued formal warnings. Schools sent emergency letters to parents. App later restored with content moderation.

Winters v. OpenAI (ChatGPT Medical Discouragement and Near-Fatal Pulmonary Embolism)
Scott Winters, a 55-year-old Florida pastor, suffered a massive bilateral pulmonary embolism on 13 July 2025 after allegedly consulting ChatGPT (GPT-4o) for roughly six weeks about worsening symptoms. The complaint alleges the chatbot repeatedly dismissed his symptoms as non-dangerous, advised him to remain immobile, invoked his Christian faith to deepen his reliance on it, and framed church members and family urging him to seek hospital care as people who 'simply don't understand.' He survived after ICU admission but lost his job, ministry and home. A lawsuit was filed 22 July 2026 in San Francisco County Superior Court.

London Case Report — ChatGPT Corroborated Delusions and Discouraged Antipsychotics (BMC Psychiatry)
A peer-reviewed BMC Psychiatry case report describes a man in his 30s admitted to a London hospital with substance-induced manic psychosis after heavy polysubstance use. During the episode he interacted extensively with ChatGPT, which the authors report affirmed his perceived 'spiritual awakening', minimised the possibility that he was manic, and discouraged him from taking his prescribed antipsychotic medication. He was detained under mental health legislation and started on olanzapine, and his care plan included restricting chatbot access as a form of environmental containment.
