The information displayed in the AIM should not be reported as representing the official views of the OECD or of its member countries.

Virgin Media O2 deployed an AI-powered system, Call Defence, to analyze and label over 1 billion suspected scam and spam calls to O2 customers in the UK. The adaptive AI warns users or blocks fraudulent calls, significantly reducing the risk of scams impersonating companies like Amazon and HSBC.[AI generated]

Why's our monitor labelling this an incident or hazard?

The article explicitly mentions the use of Adaptive AI to analyze phone numbers and identify scam or spam calls, which is an AI system involved in the use phase. The system's role directly leads to harm prevention by reducing the risk of customers falling victim to phone scams impersonating companies like Amazon and HSBC. Since the AI system's use is directly linked to preventing harm (fraud, financial loss, privacy violations), this qualifies as an AI Incident involving harm to persons (a). The article does not describe a potential risk or future harm but an ongoing harm prevention measure, so it is not a hazard. It is not merely complementary information because the main focus is on the AI system's active role in harm prevention, not just an update or governance response. Therefore, this event is best classified as an AI Incident.[AI generated]

Why's our monitor labelling this an incident or hazard?
An AI system is explicitly involved, as the Call Defence system uses adaptive AI to analyze call behavior and label or block scam calls. The use of this AI system directly prevents harm to customers by reducing their exposure to scam calls, which can lead to financial loss or privacy violations. Since the AI system's use has directly led to harm prevention and protection of customers, this qualifies as an AI Incident under the definition of harm to persons or communities. The article does not describe a potential or future risk but an ongoing protective use of AI that mitigates harm.

Why's our monitor labelling this an incident or hazard?
The AI system is explicitly mentioned as being used to detect and label scam calls, which are a form of fraud causing harm to individuals. The system's deployment has directly led to reduced answering of scam calls and shorter call durations, indicating harm prevention. This meets the criteria for an AI Incident because the AI system's use directly leads to harm reduction (injury or harm to people) by protecting customers from scams. The article does not describe potential or future harm but actual ongoing harm mitigation, so it is not an AI Hazard or Complementary Information. The TV content addition is unrelated to AI harm and does not affect the classification.
