Or should they all just be called whore? Or maybe given a number like the one they will get in prison later...

yeah, they need names so all of the sick fucks out there (myself included) can know who is who, numbers would be to confusing. Just imagine going to the local porno shop and asking if they have a feature staring "Whore #6194638172"

Yes, they do. Reducing them to mere numbers would take away the pathos and thus make their degradation and humiliation far less compelling.

I agree with you simp; although, I would like to offer a twist to that thought. By giving them numbers instead it actually increases the dehumanization and breaks down any semblance of individuality and personality. With the number the whore is just a grouping of holes to be crammed with cock nothing more. Gone are the vestiges of identity and significance inherited via that construct. Perhaps this could lead to a catharsis and help her to understand that is her true role in porn.
I know this is twisted but I can’t help it.
