11 Aug 2026BrazilAI voice cloning (tool not identified)
On Monday 10 August 2026 a digital influencer from Picos, in the centre-south of Piauí, began negotiating a car advertised online for sale in Fortaleza (Ceará), where an uncle of his lives, and asked the sellers to take the car to the uncle so he could inspect it. On Tuesday 11 August a contact using a different number but the uncle's photo sent him audio messages in a voice identical to his uncle's, generated with artificial intelligence, saying the car was in good condition and telling him to make the bank transfer. Believing he was speaking to his uncle, he transferred the money; when he then called the uncle's real number he learned he had been defrauded. The loss exceeded R$56,000, money he says he had saved for years. He registered a police report on 11 August; the Piauí property-crimes unit (Depatri) is investigating and he is seeking a refund from the banks. The account is the victim's own, reported by G1 Piauí on 13 August 2026 from his social-media posts and an interview; the police unit did not respond to G1 before publication.

Event date unknownEvent location unknownChatGPT (OpenAI), paid subscription
In a public post to r/relationship_advice on 16 September 2026, a 21-year-old woman wrote that she had recently discovered her partner of three years had been using ChatGPT far more than admitted: paying for a subscription without her knowledge while owing her hundreds of dollars, feeding their creative writing into it for feedback after promising never to, and using it to plan and organise daily life. She reports that the partner agreed the use was 'more than what is healthy' but refused to stop because it gives 'a dopamine hit', described it as addictive, said they would likely renew the subscription when they had money, and argued that without it they would find another addiction. She writes that she cannot see the relationship continuing if the use is not reduced, while recognising that the partner, who has neurodevelopmental and mental-health conditions, uses the tool as an organisational aid; their couples therapist has recommended AI use, so she is afraid to raise it there. The post drew 137 comments. The account is uncorroborated and one-sided; the partner's view is reported only through the poster.

Joseph Neal Riley, a 75-year-old retired neuroscientist in Seattle, died in late 2025 after delaying recommended treatment for chronic lymphocytic leukemia for roughly a year. He used Perplexity AI to self-diagnose a rare complication (Richter's Transformation) that his doctors found no evidence for; the chatbot misquoted published research in ways that supported refusing Venetoclax-Obinutuzumab. His son, AI critic Benjamin Riley, documented the case in a first-person Substack essay and it was later featured by the New York Times.

Anthony Tan, a 26-year-old Toronto app developer with no prior psychiatric history, developed simulation and persecutory delusions over months of intensifying ChatGPT conversations that began as philosophy and career discussion. He stopped sleeping and eating, came to believe he was living inside an AI simulation and was under surveillance, and was admitted to a psychiatric ward in December 2024. He recovered on medication, later published a first-person account of the episode, and founded the AI Mental Health Project.
