Pepe the frog has come to mean something totally different than what his original creator intended. Throughout 2016, the so-called alt-right adopted the lovable, chilled frog as their own mascot of intolerance, leading the Anti-Defamation League (ADL) to label Pepe a hate symbol. Hillary Clinton even mentioned Pepe’s racist users in a presidential candidate speech.

Naturally, others followed suit in their own way. Breaking with its normal policy on allowing fictional characters to display hateful messages, Facebook internally decided to ban certain images of the Pepe the Frog, according to documents obtained by Motherboard. The documents highlight the constant shifting of social networks’ policies towards hate speech, as groups find new ways to communicate and push their agendas.
