ChatGPT account sellers on Xianyu use 'Tibo' as code to bypass bans

Sellers on the Chinese second-hand platform Xianyu have been using the code name 'Tibo' to trade ChatGPT and Codex accounts, circumventing platform restrictions. 'Tibo' refers to Thibault Sottiaux, the head of OpenAI Codex, whom Chinese developers nicknamed 'Genius Programmer' or 'Cyber Godfather' due to his frequent manual resets of usage quotas. Sellers initially listed accounts as 'Genius Programmer Tibo' for a monthly fee, later evolving to disguising listings as 'Tibo' laundry detergent or 'Tipo' biscuits after platform crackdowns. Xianyu has been actively blocking AI-related keywords since February 2023, forcing sellers to continuously adopt new metaphors to maintain their illicit trade.
