It's been more than a month since I have started using stackoverflow. It has these users with user names in the format of "user-random number". I have observed them in some of the stack activities, most of the time asking questions.
Does the moderators create them for their own purpose. If yes what purpose do they serve?
I mean a user is free to have any user name. But it's just a hunch that such users are actually moderators. I may be wrong; just need some clarification.
