Launched in 2007, tumblr became a safe haven for LGBT youth, a launch pad for social justice movements, a NSFW rabbithole, and a counselling station for mental health issues. For a decade, this micro-blogging platform had more users than Twitter and Snapchat, but remained an obscure subculture for non-users and most researchers. In 2018 it catapulted to popular consciousness by banning all NSFW content, shifting to rigid censorship almost overnight.
