The secret lives of Facebook moderators in America.

The expansion of private-security contractors in Iraq and Afghanistan is well known. But armed security personnel account for only about sixteen per cent of the over-all contracting force. The vast majority—more than sixty per cent of the total in Iraq—aren’t hired guns but hired hands. These workers, primarily from South Asia and Africa, often live in barbed-wire compounds on U.S. bases, eat at meagre chow halls, and host dance parties featuring Nepalese romance ballads and Ugandan church songs. A large number are employed by fly-by-night subcontractors who are financed by the American taxpayer but who often operate outside the law.
