A person who repeatedly used the Taipei Metro AI customer service system to send threatening messages has been sentenced to six months in prison, marking the first conviction involving misuse of the platform. The sentence may be commuted to a fine in accordance with the law.

The suspect repeatedly sent threatening messages through the AI customer service platform. After Taipei Metro reported the case, police identified the suspect, and prosecutors filed charges for public intimidation after determining the messages were intended to cause public panic.

The Taipei District Court found the evidence sufficient and sentenced the defendant to six months in prison, with the option of commutation to a fine. The case may still be appealed.

The AI customer service system provides passengers with travel information, lost-and-found assistance, and inquiry services. Taipei Metro said any attempt to interfere with the system or use the platform to spread threatening messages or engage in other illegal activities will be documented and reported to police to help safeguard Metro operations and ensure normal system functions.
