>>Before they leave their home country, the future prostitutes are taken to a sorcerer. The man takes samples of hair, pubic hair and nails; and he puts it all in a box. Simultaneously, he incises their skin and introduces in the wounds a decoction made with herbs and blood. In doing so, according to the African tradition "juju," the sorcerer gains control over the young women to such a degree that he can kill them or drive them crazy remotely if they don't repay their debts.
>>"Prostitution networks very often use the figure of Eshu, the god of players and cheats, a character known for traveling inside people's dreams," says Stephan Fuchs, a Nigerian migration expert and founder of the website Trafficking.ch. "From early in childhood, these girls have been living in a world where magic was everywhere, so they're terrified. They're so certain that something will happen to them if they disobey that, once the ritual is over, they behave like their recruiters' slaves."
Interesting point about using a deity / magic as a means of enslavement.
