Cloudsurf, there probably is a bigger appeal for SB in the U.S. In some cities, law enforcement has gone after the escort business. It's random and it's real. You can always stick to the same escorts, but if they retire or you want some variety Seeking.com seems like a good route. Given the upward price pressure here for attractive, young escorts, the economics don't seem so bad. Not everyone can just jump in a car and drive to Montreal.
It sounds like SB is a form of escorting for some girls. I know some will disagree. It's just a subjective assessment from reading the accounts here. I'm not a Law Enforcement expert. I am cautious so I don't have to worry about the law. Seeking.com and the entire dance between the guys and the girls would seem to give men and women legal cover.
Having said that, I wouldn't be surprised to see some enterprising local LE go after Seeking.com participants. Frankly, a few of the girls' profiles sound like escorts. They're clearly up for anything. If we use Jalimon's approach with a strong P4P intro, I can see that being problematic with the law at some point. On the flip side, if you are having coffee, lunch, etc. before you get too explicit, the police will have no time for such a long game.
