YouTube shooter's bizarre videos key to suspected motive

The woman who shot three people at YouTube's headquarters was prolific at producing videos and posting them online, many of them bizarre, such as a clip in which she removes a revealing purple dress to expose fake, strapped on breasts with the message, "Don't Trust Your Eyes."
"Youtube filtered my channels to keep them from getting views!" one of the messages said. "There is no equal growth opportunity on YOUTUBE or any other video sharing site, your channel will grow if they want to!!!!!"
