I am being thick, but are you saying the ones who are pimped are trafficked or not?
A fair question, and it demonstrates how media fervour which insists on using emotive, sensationalist terms doesn't really help.
I suppose we all have our definitions, mine would be...
Woman travels from Romania via EU free movement rules, gets in touch with someone who deals with accommodation, profiles, client etc. for a cut (usually a sizeable one) = PIMPED.
Woman travels against her will under threat of harm in the first place, doesn't really matter what happens beyond that = TRAFFICKED.
Both practices are pretty horrible in my view, I've yet to hear of a 'good' pimp.
