The 2018 YouTube Headquarters Shooting refers to an incident on April 3, 2018, when Nasim Aghdam opened fire at the company's San Bruno office. While the event was a tragedy, it entered internet culture primarily through the perpetrator's eccentric online presence. Aghdam was a prolific content creator who posted bizarre fitness videos, vegan activism, and parodies, often complaining about YouTube’s censorship and demonetization policies. In internet circles, the 'meme' version of this event usually revolves around screenshots of her surreal videos or her manifesto against corporate gatekeeping, often used as a dark commentary on the frustrations creators face with platform algorithms and content moderation.
