I'd thought the definition of "trafficked" was someone held  in slavery,  or underage, or taken from one country to another against their will to provide illegal services.  But they seem to be using "trafficked" as applying to any adult woman who chooses prostitution.    

This tendency to hold women blameless for their choices has strong similarities to the pro-life strategy of calling all women who freely choose to have abortions as "victims" of Planned Parenthood.
