They're pooinloos and gooks from offshore companies. Facebook hires them to comb through complaints much like companies hire them for call centers.
Prove it
Literally the first Google result you utter fucking mong. Jesus Christ, kys.
"The campuses of the tech industry are famous for their lavish cafeterias, cushy shuttles, and on-site laundry services. But on a muggy February afternoon, some of these companies’ most important work is being done 7,000 miles away, on the second floor of a former elementary school at the end of a row of auto mechanics’ stalls in Bacoor, a gritty Filipino town 13 miles southwest of Manila."
"This work is increasingly done in the Philippines. A former US colony, the Philippines has maintained close cultural ties to the United States, which content moderation companies say helps Filipinos determine what Americans find offensive. And moderators in the Philippines can be hired for a fraction of American wages. Ryan Cardeno, a former contractor for Microsoft in the Philippines, told me that he made $500 per month by the end of his three-and-a-half-year tenure with outsourcing firm Sykes. Last year, Cardeno was offered $312 per month by another firm to moderate content for Facebook, paltry even by industry standards."

That you can't be bothered to Google this shit for yourself is why you're a fucking basement-dwelling kittenfucker.
The reason that Facebook outsources this service should be immediately obvious: It is an extremely labor-intensive task to sort through the tremendous volume of complaints and flags to filter out valid TOS violations from malicious or accidental flagging.
FB has attempted, rather unsuccessfully, to add automated algorithms for determining what is a validly-flagged post, page, or profile–and these algos have mostly been based on the volumes of reports. (i.e., if a certain threshold is reached, the element in question is automatically banned, if only temporarily).
The other interesting tidbit is that a lot of this hired help is Muslim, which is why for a period of time reported content that was critical of Islam was getting taken down very quickly and en masse; the muzzies doing the moderating were going full Shariah on the content. (This was before the current site-wide campaign against "hate speech.")
