T-Bill, I believe you're skating on thin ice.
Let me explain... If indeed you are discovering "new" talent and provide for them a means to profit from this particular endeavor (regardless of how that is achieved), you are indeed crossing the line.
What probably makes Fred extremely nervous, and personally, I don't blame him, is the fact that these girls are new. LE certainly has a presense on this board and if I were a betting man, your girls would be the easiest by far to shake down in a sting. They may not be saying shit now but put them under an intense interrogation and see how well they sing! Do you have the wherewithal to ascertain who is trustworthy in this regard and who is not? And with no business registration, you're a sitting duck. The assumption would be that you aren't paying taxes either. All the more reason for LE to investigate.
Agencies depend on other girls within the establishment to "educate" them on proper escort ettiquette. For the owner to directly involve himself/herself in that particular activity, well... the implications are rather obvious.
Just from what I've read, you could easily be charged for Exercising Control (arranging the meetings, discussing the nature of the business directly, and indirectly, by exposing them to TERB, etc); Living Off The Avails (compensation for your efforts regardless of the means); and Procuring. I'm not a lawyer, but I do understand the lattitude that police have in laying charges such as these.
It wouldn't be difficult to paint your actions as that of a predatorial monster. No matter how noble and selfless your true intentions may be, if they have a sobbing naiive witness (or two) giving statements to a video camera, bet on being indicted. It ain't hard to coerce them into this position while under threat of going to jail themselves. Hell, most of them truly don't know what their rights are! Getting a conviction is another story. But it's a no-brainer that what you are doing is dancing precariously on the edge of danger for if it ever came down between you and a working girl under the threat of jail... guess what? You lose.
As for Fred's stand on some kind of validation, I heartily agree. Two reasons: The first one had already been stated so really needs no mention here. The second one does as it appears that no one has discussed the "harrassement" angle. What if the Yahoo link or e-mail address was the result of some girl playing a nasty joke?
Suddenly, some old lady in bum-fuck-Idaho starts getting these lewd and suggestive e-mails and freaks. Cops get involved... a trace discovers it's coming from Toronto... yada yada yada. If it was initiated through Fred's board, he's toast as well as you T-Bill, or whoever engages in this practise. Regardless of how innocently it all began, it can land some people in deep doo doo.
3rd. party verification acknowledges that they are indeed who they say they are.
It's just my opinion so I hope you don't take offense.
