If this is the only think she ever did for you why does she still have a stage name

The "stage name " is something who doesn't depend of the fact she did or not a scene.
It can be for two reasons :

1) when a girl she sign the model release, she can imediatly request ( or me to propose ) a stage name which is written on the paper.

2) She don't write any stage name because she don't have any idea and me too, but if when I publish, she already got one from the business she does in other places, and I know it, then I publish her with that name.

The only problem is when a girl write something today and then has already changed the day of publication, it's a bit stupid but often like that ...
