While researching today, I felt as though I had fallen of the planet and into some crazy Star Wars crossed with Indiana Jones kinda story. The African concept of Trokosi. Briefly its the selecting of a child, usually a virgin female to serve in a shrine for the crimes committed by another family member. Basically we're talking traditional religious crime control. Its practised by groups like the Dangme, Ewe and Fon of West African countries like Benin, Ghana and Togo.
Trokosi's comes in 3 flavours, which I will arrange from most to least humane. Dorfleviwo or Baviwo get offered by their parents to serve the Gods in appreciation of their role in the child's conception and birth. Fiasidis may be given by their families, inducted by the deities, or voluntarily chosen to serve in shrines. They are the “wives of the gods” and are treated with respect (go figure) and may own property. The un-pretty version of Trokosi is the atonement on behalf of other family members type.
Although a Trokosi should only spend between 6 months and 3 years in servitude, depending on the gravity of the family members offence, they are often stigmatised and feared in their communties and so their families often don't secure their release and they are forced to serve at the shrines for the remainder of their lives or until they become sexually unattractive (who decides this shit???). They perform free labour ( one can only imagine the type ) for those that run the shrine so its basically bondage or slavery playing dress up, paying for someone else's crimes. To make matters worse Trokosi's have to wear blue-black cloth and the identification Raffia necklace at all times, so that people can see you a mile away and can get a head start deciding how they are going to abuse you.
