OpenAI banned a cluster of ChatGPT accounts and one API customer that very likely originated in Cambodia and used AI to run a semi-automated romance and task scam targeting Indonesian loveseekers.
The operation used ChatGPT to generate promotional texts, pose as a flirtatious receptionist, translate messages, and create fake dating platforms.
OpenAI states its policies strictly prohibit use of its tools for fraud or scams.
