The NBC Bay Area Investigative Unit has confirmed the identity of the shooter who opened fire on YouTube’s campus in San Bruno Tuesday. Nasim Aghdam, 39, lived in Southern California and appears to have had a robust presence on YouTube.

In a video posted in January 2017, she says YouTube “discriminated and filtered” her content. In the video, Aghdam says her channel used to get lots of views but that after being “filtered” by the company, it received far fewer views.

In one online rant, she complained that YouTube censored her content by imposing an age restriction on one of her workout videos because they were too racy. She says the company failed to do the same thing for stars like Miley Cyrus and Nicki Minaj, whose videos, she says, are inappropriate for children.
