Facebook has come under fire for allowing the “barbaric use of technology” that led to a girl in South Sudan being married off to the highest bidder.An auction was held on Facebook for a 16-year-old girl in order to drive up her dowry. Plan International reports that five men placed competing bids, some of whom are high-ranking South Sudanese government officials.The girl’s father ended up receiving 500 cows, three cars, and $10,000 in exchange for his daughter through to the Facebook auction.Facebook, for its part, took 15 days to take down the post — originally posted on October 25 — but by this time the girl had already been married off.As CNN reports, activists are scared this case could inspire other families.
