ChatGPT suddenly faces suspension controversy, $200 Pro users also affected

Multiple users report that ChatGPT accounts have been suddenly suspended, including Pro users paying $200 per month. Some users did not receive notification and cannot access chat history. Users suspect it is related to using VPN, but OpenAI Support replied that appeals must be made through official channels, without explaining the specific reason. The official list of suspension reasons includes policy violation, security anomalies, and regional access restrictions, but did not confirm if it was a coordinated action.
