I appreciate your concern about the naming and I think you are right to have that concern. The problem with this (to be obvious) is that 'black' is being used as an perjorative because there are good markets and bad markets but the good ones don't have an adjective, and 'black' is an attribute which is also used to describe people who are born with darker skin (perhaps unavoidably so, for the forseeable future).

Is there a reason can't you just call this a Slave Market ? I mean, wikipedia has a page entitled just that: https://en.wikipedia.org/wiki/Slave_market. If you wish to disambiguate from historical you could add 'modern', 'contemporary', 'underground', or 'secret' very easily.

As to the location, it might be the case that the middle east is where you were involved, but I rather suspect that a) not all the slaves sold remain in that area and b) this does not only happen in that area. Certainly I have read of modern slavery occurring here in the UK and elsewhere in Europe. I have certainly read of women from China, Nigeria and Eastern European countries for instance, being trafficked for prostitution in recent years and I'm pretty sure that this is not the whole story. You are doing great work[0] actively working against slavery, right? If your organisation were successful in the middle east, would it then simply close down?
