Forum:How does the Wikia bot pick which user pages to plop a "no-clog" notice on?

Just out of curiosity, how does the Wikia bot user pick when to plop one of these on a user page: "This brief blurb was placed here to eliminate x's user page from clogging up Wanted Pages. If you are the user, please feel free to let the public know a little more about you and your contributions." I've noticed that it seems to leave most uncreated user pages go, while it apparently picks users at random to do this with. I've even noticed on the user creation log, that (for example) three users will be created not too far away from each other time-wise, and one of them (but not the other two) is given a "brief blurb". Does anyone know why this is? It's been driving me kind of crazy with curiosity. :-) Thanks, -Mdettweiler 05:59, January 2, 2010 (UTC)

The reason why I didn't think that was the case was that when I first registered, I made quite a few edits without having a user page. Eventually I decided to get it over with and put my own "brief blurb" there. :-) Oh well, not that it matters too much. -Mdettweiler 01:22, January 3, 2010 (UTC)

Ah, okay, that makes sense. Thanks for the explanation. :-) -Mdettweiler 01:32, January 3, 2010 (UTC)
