I typed https://stackexchange.com/users/0 and found there is a user with #0 named RAKESH KUMAR.

enter image description here

Community user is user #-1
Jeff Atwood is user #1

Who is this user #0? Are they a co-founder or developer of SE or SO? Or is this some kind of bug? They don't have any SE account (may be deleted later ?)


There were actually two users with a network account Id set to 0, both of them created at about the same time. I can only imagine that there was some short-lived glitch in the database back in 2019 that has not reoccurred. Both the profiles have now been deleted, given it's pretty much impossible to track down a real account or what happened without a correct account Id to investigate.
