Fake Twitter

Last night, a woman opened fire with a handgun at YouTube’s headquarters in Silicon Valley, shooting three people before killing herself. As soon as shots were fired, YouTube employees and those in the local area began documenting the incident on Twitter.

Just as quickly, fake news took hold. Online misinformation is now a part of every tragedy, but what was striking about last night was just how quickly and forcefully the hoaxes and trolls started and spread.

Vadim Lavrusik, the YouTube employee whose original tweet alerted many to the shooting, had his account hacked. Reporters identified dozens of tweets that appeared to be spreading misinformation on purpose.
