Users only upload their government ID to Discord when the "Face Scan" [0] incorrectly estimates their age as being less than 18. Discord could reasonably classify this as a "small number" of users who need to upload their government ID image. That wouldn't preclude it from also being every user who needs to upload their government ID image — unless there is some other system that also requires them to upload it?
With that in mind, here's a rephrasing of the same statement:
> The unauthorized party also gained access to all uploaded government ID images.
Their press release does NOT say it's a small subset of photo IDs. It says a "small number" of government ID images — nothing about percentages. This would be consistent with the "small number" of users who need/choose to appeal an incorrect age estimation from Face Scan.
