I have to admit, I saw my first ever Brazillian the other week and this was a nagging concern at the back of my mind, although I didn't see any evidence of anything untoward. In any case, I'll be sticking to the local talent from now on.
We do have to accept that coercion control is part of the sex industry, and be aware of the possibility that anyone (even 'locals' and 'agency girls') can be subject to it. I always try to tread carefully and avoid any situation that has a hint of something not right about it, but maybe I'm just kidding myself about my detective capabilities.
I'll give the program a watch. Thanks for the info.
