Literally anyone can be a whore and literally anyone can monetise a thousand sleazer gang bang. The fact that BB is so disgusting, repellent and foul is the reason she makes so much money, even in the world of prostitution she's an aberration. Lining men up to piss on your baby bump is pathetically wretched and putrid, for example, you'd have to be a psychopath or irreparably damaged to think otherwise, and that goes for everyone involved obviously.
A fat, ugly woman willing to let a thousand men gang bang up her an alley would also find it easy enough to monetise. BB does nothing special, she just takes painkillers, spreads her legs and tells men to do whatever they like by the thousand. Having an actual job is beyond her. Being a whore is the easiest task in the world and anybody at all can do it, fat, thin, old, young, disability, nearly dead, doesn't matter.
I know that OF prostitutes don't make much cash, and that's because most of them aren't willing to lie in the street spread eagled letting rapists use them by the thousand, they all think they'll be able to just play around with their boyfriend on camera and make cash, they realise pretty quickly that once they're no longer new flesh on the market that they have to do really vile things to make any real money. I read a couple of pieces by OF prostitutes a couple of years back, and it's all so grubby and sad.
That's why the OF prostitution site is a pyramid scheme - they all get 5% of newbie earnings if they can sign them up as a referral. Like Tupperware ladies with STDs, prolapsed vaginas, drug addictions and PTSD. They can't make much money unless they do something extraordinarily gross, like BB.
A particular sort of man will fuck animals and a car exhaust, so the point I was making is that it's in no way special or difficult to be a depraved whore, like BB, you just have to have absolutely zero self esteem and no boundaries at all.
