Unfortunately the people going after BP for the escort section are lacking in the sense department.

"It appears that limiting sex ads in one place won’t reduce threats to women and girls but merely push it someplace else, he said."

Sorry, but I just don't believe there is that much child trafficking in the twin cities. As long as I've been engaging in this hobby, I have never seen a lady that I thought was under aged. I can't imagine any sane man hooking up with an under aged girl. Can you imagine the embarrassment to your family let alone the prison time. I just can't believe that many men are that stupid!

Well, I suggest you google news stories on the matter.  While LE grossly exaggerates the level of human trafficking, it is not hard to find cases where people have trafficked underage girls and guys have been arrested specifically for that; i.e., they wanted to see girls who were underage.

I never said it doesn't happen, only that it's not as prevalent as they say. Have you ever seen a girl that you were sure was under age while hobbying? Not me and if I ever did I sure as hell wouldn't hire her. I would probably try and help her get out.

If I'm concerned about her age, I steer clear to begin with.
