The /r9k/ board, short for ROBOT9000, was originally created by Randall Munroe of xkcd to foster original content by using a script that bans duplicate text. Over time, it evolved into a distinct subculture populated by self-described 'Robots'—individuals who often post about social isolation, 'feels' stories, and niche internet tropes like 'tendies' and Pepe the Frog. The /r9k/ meme style is most famous for the 'greentext' format, where stories are told in short, bulleted lines starting with a 'greater than' symbol. It has become a central hub for some of the internet's most recognizable reaction images and linguistic quirks, reflecting a mix of self-deprecation, irony, and shared digital loneliness.
