And I did the same as a kid in the late 2000s in order to play World of Warcraft. Found someone’s info on a random online dump, filled it in and didn’t think more about the id theft. What I then learned is that there is NO “fake” IDs that can pass this test. It’s just plain old ID theft of actual people.
The ID itself is encoded as 3-digit city/3-digit district/8-digit dob/and 4 random digits. There is no “generated” name that works with a specific ID since the name isn’t encoded anywhere. Most reputable vendors perform the check backed by an actual government DB.
The problem is that it IS the exact same info used to apply for bank accounts, loans, mobile phone numbers, etc. And nobody bats an eye when a pirated gaming app asks for it. This could be legitimate, but I’m more willing to say this is someone’s ID collection scheme. If that’s the case, it could be doing more than just collecting IDs (cause why not?) or it’s at least facilitating more ID theft.
