I actually had the experience of meeting one once. The red flags of a hooker were there immediately, wanted to meet immediately, no first date public meeting, etc etc, which I was ok with as I "like" hookers, but the shocker was when we were discussing "allowance" in person after she admitted she had been "dropped off" and wasn't driving herself as she had told me at first, she made a statement that she would "get in trouble" if she didn't collect a certain amount, (I don't remember or care what the actual amount was)., Something in my brain just snapped with the realization she was not just a hooker, but a pimped hooker to boot.
I don't know about the rest of you, but I absolutely refuse to enrich a pimp or help facilitate the pimping of women or girls. (or boys too I suppose, but I don't roll that way. lol) When she said that "she would get in trouble" it was like someone hit me in the face, I IMMEDIATELY threw her out of my house and informed her that if her driver/manager had an issue with me he was more than welcome to take it up with me personally, I did warn her that I was likely to shoot him right through the fucking front door instead of answering though. lol She wasn't happy, but she left without causing a scene.
After I tossed her out of my house and after waiting a suitable period of time to be sure I wouldn't have an angry pimp at my front door, I reported her to SA and her profile was deleted by the next day.
I won't say this is a huge problem on SA, but I can say first hand that it does happen.
