Crazy begets crazy.
These girls who are obviously unstable get taken advantage of far more than the types who intentionally build a porn career with calculated movements. Someone like JJ typically enters because they have no choice but to do porn. They're not able to formulate a methodical plan with precise steps and a defined exit.
Someone like, idk, Xxlayna Marie ain't getting worked over by a manager.
Anyway, I genuinely feel bad for JJ, but I can't see her crashing out as anything but inevitable.
