Most people on here tend to like to suspend logic and go with the fantasy with many of the posters, which is fine.
But before you were to talk with one of these "women" on the phone or meet up with in real life, one thing I would highly reccommend is asking them to hold up a hand written sign that says "fight," "catfight" or "free catfights" on it before you do anything.
As a producer, when we are contacted by a beauty that seems to be too good to be true, this gives us a way to verify that we are actually dealing with a woman.
