Facebook troll farms

September 2021

Trolls farms account for over 40% of content people in the US consume on Facebook every month, according to a Facebook document authored in October 2019 by Jeff Allen, a former data scientist at the company, that was leaked to the Technology Review.

Largely based in the Balkans, the troll farms targeted four primary groups: American Indians, Black Americans, Christian Americans, and American women.

According to the Technology Review, Allen left Facebook shortly after writing the document, partly because the company 'effectively ignored' his research.
