In a Tuesday blog post, Facebook VP of Integrity Guy Rosen announced that the platform would be updating its hate speech policy and would be banning all images and videos of blackface, including the traditional Dutch blackface Christmas character “Zwarte Piet.” 

Portrayed as a sidekick to Sinterklaas (the Benelux version of Santa Claus), Zwarte Piet—literally "Black Pete" in English—is traditionally played by adult white men who wear full blackface, earrings, curly-haired wigs, and exaggerated red lipstick.
