Just did a search for professional pornstar in p411. It seems girls with a premium Snap chat or only fans consider themselves professionals. What makes someone a professional? I feel like that search is less and less accurate as time goes by.

Don't blame the porn stars.  This goes back to Hollywood.  Everyone that gets billing in the picture is a "movie star."  It just means actor/actress these days.   I would imagine cam shows are as good for porn as live TV is for TV stars.

For instance, Stanley Spadowski ... world's best janitor and TV star.

Yea I think the same.
