I came across the same phenomenon when researching an article on Sienna Miller: the 18th-century idea that young actresses are little different to common prostitutes is alive and thriving through 21st-century technology.
Umm, no, not quite. There is indeed a certain level of young actresses who are so thought of but they are referred to more often as a MAW (Model, Actress, Whatever). The W part being the clue. Ashley Dupree being an example, although the lower levels of B movies and so on are full of this sort of personnel.
