Most of us know providers we are *sure* are independent and in the business by choice.  But it's really hard to know for sure.  Trafficking is insidious - and it's NOT relegated to BP and Asian or Mexican brothels.  Though you rarely hear or read about it (because it tends to be much harder for law enforcement to build a case), there are American-born providers with great websites, donations in the $$$ to $$$$ range, and hosting at 4 star hotels who are in the business by coercion, but whose day-to-day well-being depends on making sure clients believe they are independent and in the business by choice.
