Did you show your face to Discord for verification? Your data is already close to being leaked online
Security researchers have discovered that Persona (Discord's age verification partner in the UK) left the frontend code of its system publicly accessible on the internet in the form of over 2400 source code files and source maps on a US government server (FedRAMP). So far, there is no information about a leak of data from users who have undergone age verification, but such "slip-ups" significantly facilitate the process for interested parties to gain access to sensitive data.
It is also worth understanding that Persona's system is also used by OpenAI for ChatGPT and many other companies. The most important aspect of the leaked data is the scale of user surveillance. Persona not only fails to delete user facial data after age verification, but also retains a lot of other data.
