Buzzfeed reporter Ellie Hall got a disturbing look at the online world of young women — often from the West — who claim to be members of the Islamic militant group known as ISIS. They go to the Middle East to be married, raise young Jihadists and spread propaganda on social networks.

ISIS knows media and messaging, from its black and white flag to its raised index finger gesture to its tweets. Now the group has a new propaganda wing that is producing sophisticated, effects-laden videos in styles from rock videos to action movies.

More than half of all Iraqis are under the age of 20. But as most of the country is gripped by violence and instability, opportunities for young Iraqis are evaporating, and more and more are emigrating abroad. One group of friends say they’re determined to break that trend.

When you go to the hospital, you give up a lot of very personal data, not the least of which is your name, address and Social Security number.
