The following is an anecdotal account from my mother which I recall from memory:
She was in the changing room of a clothing store (in Athens, during the 80's or 90's) and overheard the attendant, who had in the past conspired in abducting young women to supply a harem, and who was relaying the story to a friend of hers.
The incident was made memorable to her because of the method they used: They would put an ad in the paper looking for an actress or dancer (or similar), and during the interview they would tell the victim that it's a very small role, won't take too long, no need to tell your family or friends. That's pretty much what she overheard, and told me a similar offer had been made to her while looking for work some time prior to that.
She also remarked that this method had pretty much died out nowadays (late 90's at the time) due to the collapse of the Soviet Union, and the supply of emigrants from these countries.
I'll ask for more details when we next speak and update this answer accordingly. Again, this is an anecdotal account which I relay from memory, so take it with a generous pinch of salt.
More info: The year was probably '87 and it wasn't the attendant who was part of the scheme, it was her friend, who was in his 50s and recently out of jail. The shop was in the affluent area of Kolonaki. The ads would be put in the Ta Nea (The News) newspaper.
My mother was looking for work in '83 and went for an interview, to a rented-out dance hall in the Athenian suburb of Kallithea. There, there was a man and a woman, who introduced themselves as husband and wife. They were looking for a group of dancers or extras to send to Australia, with a stopover in the Middle East. The guy was very excited about her but she didn't like his look for some reason, and after a while another woman came in, whom they took away and introduced themselves as brother and sister.
So, there you go, straight from an Internet stranger's mother's horse's mouth.
