Islamic State sex slaves are being sold on Facebook it has been revealed after several posts were deleted by Facebook for advertising young slaves for sale.

“To all the brothers thinking about buying a slave, this one is $8,000,” wrote ISIS soldier Abu Assad Almani in a Facebook post, along with a picture of a girl described to be around the age of 18. “Another sabiyah [slave], also about $8,000… Yay, or nay?” read another one along with a picture of a young girl described to have “weepy red eyes.”

Both posts were deleted by Facebook within hours, but it has revealed the depraved next steps that ISIS militants are willing to take in order to fund their campaign of jihadi terror.

Almani’s posts were tracked by online terror watchdog, the Middle East Media Research Institute, who monitor Islamic terrorists online, and managed to see the posts before they were deleted by Facebook.

“We have seen a great deal of brutality, but the content that ISIS has been disseminating over the past two years has surpassed it all for sheer evil,” said Institute director Steven Stalinsky. “Sales of slave girls on social media is just one more example of this.”

Comments on the posts were equally as disturbing according to reporter Joby Warrick.

“What makes her worth that price? Does she have an exceptional skill?” wrote one of Almani’s friends in a comment one of the photos.

“Nope,” replied Almani. “Supply and demand makes her that price.”

Other comments reportedly mocked the slaves for their appearance, discussed the price of the girls with Almani, and complained that the girls were not wearing a religious veil.

According to the UN’s ISIS sex slave price list published last year, children aged between 1 and 9 years old can be sold for around $165. Adolescent girls are mildly cheaper at around $124, while women over 40 who are considered old for ISIS fighters go for as little as $41. Almani’s huge increase in prices further demonstrates how much money the Islamic State has lost since last year, with airstrikes taking out the majority of ISIS-controlled oil rigs and compounds.

Facebook’s removal of the ISIS posts were swift, being completed in just a few hours, but some conservative commentators have found their posts being removed even quicker, and for no substantial reason at all. Libertarian Canadian commentator Lauren Southern received a 30-day Facebook ban after defending a popular conservative page admin who had also been banned. The social network even deleted her post criticizing the platform for their politically-biased actions.

In December, Breitbart reported that Facebook, Twitter, and Google had also teamed up with the German government to ensure that any “hate speech” or criticism of Germany’s then-recent refugee intake would be removed within 24 hours.
