Like hundreds, or perhaps thousands, of girls from the Becheve clan who are victims of money marriages, Monica and her sister were sold without their consent. Their father wanted to clear the debt he owed to a distant relative. The two sisters got married a month apart to men whom they did not know at all and who were old enough to be their grandfathers. Their respective husbands got in touch with their father after seeing the Facebook page where he posted photos of his six daughters to draw the attention of his tribesmen. The men of the clan have found the new technology helps to extend and expand their old, exploitative traditions. -Daily Beast

"My father knew nothing about Facebook until my elder brother bought him a smartphone and convinced him to join Facebook and post our photographs whenever he likes," said 16-year-old Monica, one of two sisters who were sold to men over the social media platform. "He'll buy new clothes and force me and my sisters to put them on before taking photographs of us."

"It is young people who convince old men to look for wives on Facebook," said Monica - a former child bride who ran away from her husband to live with friends less than a year after getting married. "The man I married said his oldest son showed him my photo on Facebook and directed him to my father."

It's not just Nigeria either - last November, Facebook took heat for posts discussing the sale of a 16-year-old South Sudanese girl who was sold for 530 cows, three Land Cruiser V8 cars and $10,000 - after a bidding war broke out between five men, including senior officials in the South Sudanese government.
