Suppose I should contribute, more.
My 2 cents: I have yet to pick up a girl on the street, not sure if they'd hop on a motorcycle. And we go to her place. So I can only speak of "escorts" and I have not been busted yet. I just try to be careful and not call the "new" girl, and wait for another one to review, I although I have called without knowing %100 a few times, and it seems as if the girl acts more concerned about me being a cop. Then she is not part of a sting, I have not found a fool proof way to know if they are not a sting. Hopefully I never will need to either. Also doing a quick search for the girl, more ads, an actually site, reviews etc lean more towards not a sting.
But here is some video of busts. From a sting op.
