What is meta? ×
Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 131 Stack Exchange communities.

I was browsing around some of the other Stack Exchange sites I use and noticed that most of the ones I recently joined have two names listed under the recent names on my profile:

a25bedc5-3d09-41b8-82fb-ea6c353d75ae
Anonymous

Why would these be added?

It's currently showing these two additional display names for these profiles:

I realize that these should eventually go away, but really they shouldn't even be there. It seems that the system changes my username twice when creating and linking a new account on some other site. Why wouldn't it start my account at my actual display name at the time of creation?

Funny. Same thing for me on a site I registered to today (physics), except that it shows my real name (that I have in my profile) instead of that GUID-type thingy. –  Mat Jan 7 '12 at 19:50

Nice, that explains earlier confusion! –  Arjan Jan 7 '12 at 20:05
    
I had only noticed it on a site I moderated and presumed it was an advanced moderators feature for justifying sockpuppet bans. –  Ambo100 Jan 7 '12 at 20:34
    
I have all my accounts that displayed these two names now(first time I noticed this was at meta.SO), even the accounts that linked long time ago.. –  Kjuly Jan 8 '12 at 4:16

Great mother of Zod! A 100% accept rate on Meta? You totally have to work on that. –  Tim Post Jan 11 '12 at 22:55

This will be fixed next build; apparently (as I'm sure you guessed) new accounts start with a dummy name, that is filled in ASAP (using either the "user12345" pattern or a name from you or your OpenID provider) - news to me, since it happens very fast. In fact, you just proved a code-comment accurate:

// some random string so obnoxious people will complain about it
public const string NewUserDisplayName = "a25bedc5-3d09-41b8-82fb-ea6c353d75ae";

see, the logic was flawless!

+1 for revealing source code.. ;-D –  Shadow Wizard Jan 11 '12 at 11:16
    
Positively brilliant. That user deserves a T shirt. –  Tim Post Jan 11 '12 at 12:05
    
@TimPost: I would proudly wear that shirt! I'll even attach my Stack Overflow GOLD Nerd Merit Badge to the sleeve. :P –  animuson Jan 11 '12 at 21:48
    
I don't speak for Stack Exchange, but I think a T shirt to commemorate hitting this odd corner case would be in order. @Shog9 perhaps it's possible? I don't summon the shog unless I feel it's a moral imperative. And, well as a mod, I'm supposed to be encouraging very enthusiastic users. He does have a bit of gold to show off :) –  Tim Post Jan 11 '12 at 22:45
    
@Tim re "rare"... It would affect any account created on any given site in the last 90 days (rolling)... :p –  Marc Gravell Jan 11 '12 at 23:04
