I was also banned yesterday, and I don't think it's a language or time zone issue at least. It's not just China (such as some users in Singapore and Malaysia) who use Simplified Chinese near the East Eighth District. My IP and geographic location are mostly in Singapore, and payment is also made using a local bank card in Singapore. I think it's possible that my IP has been frequently switching between Hong Kong and Singapore in recent days, and Hong Kong is not a region supported by OpenAI. A few days before being banned, I happened to be going to Hong Kong After connecting to the local WiFi in Hong Kong, I couldn't use the ChatGPT app anymore, so I switched back to international roaming with my Singapore Telecom card and was able to use it again. I was suddenly banned after a few days of this. But I still opened a new account to subscribe to Pro, and the old account is still writing emails to appeal.
