The suspected YouTube shooter obsessed over the video-sharing site before her attack, posting online rants accusing it of censorship and likening it to Adolf Hitler.
Nasim Najafi Aghdam, who opened fire in YouTube's headquarters in San Bruno, Calif. Tuesday, used her websites, social media accounts and even YouTube channels to rail against YouTube, alleging that it was suppressing her online audience.
In one post on her personal website, she compared YouTube to a "dictatorship."
"Videos of targeted users are filtered & merely regulated, so that people can hardly see their videos!" she wrote. "There is no equal opportunity growth on YOUTUBE or any other video sharing site, your channel will grow if they want it to!!!!!"
In her rant, she also quoted Adolf Hitler for a line often incorrectly attributed to him: "Make the lie big, Make it simple, Keep saying it, And eventually they will believe it."
Aghdam maintained at least four YouTube channels. They included videos about animal rights, vegan cooking and fitness in English, Turkish and Farsi. All of her YouTube videos and social media accounts have been taken down in the aftermath of the shooting.
"I'm being discriminated and filtered on YouTube," she said in one YouTube video that has since been removed from the site. Aghdam complains in the clip that YouTube had age-restricted an ab workout video she uploaded.
“The video has nothing bad in it, nothing sexual,” she said, claiming that the site put an age restriction video to prevent it from becoming popular. Aghdam alleges that YouTube had a vendetta against her and other vegan activists.
Her grudge towards the video-sharing site had apparently been brewing for some time. Last year, she posted a photo on Facebook of her standing on a street corner with the caption "YouTube Dictatorship. Hidden policy: Promote stupidity discrimination, suppression of truth,” according to NBC News.
Aghdam wounded three people before fatally shooting herself.
