A California restaurant apologized after a promotional post on its Facebook page was published about their Las Vegas locations following the mass shooting there.
The search for Danley began after the Las Vegas police identified a woman named Marilou Danley as a person of interest and possible traveling companion of the real shooter, though law enforcement later noted they did not believe she was involved with the shooting.
The listing did not appear in Google News.
A few hours later, searches for the same name were showing articles debunking the 4chan post and cataloging the trail of viral fake news after the shooting. It described him as someone thought to be "a Democrat who liked Rachel Maddow, MoveOn.org, and associated with the anti-Trump army".
"Despite months of assurances to the contrary, the internet's two largest media platforms have yet to adequately protect their systems from enabling the viral spread of misinformation", says Forbes.

The militant group aims to oust the western-backed government in Mogadishu and drive out African Union peacekeeping troops. No group has claimed responsibility for the latest attack in the Horn of Africa country.
Facebook said its security team removed Gateway Pundit results and other similar posts from its social network, some within minutes. There are multiple reports that Danley accompanied the assailant - ID'd as Stephen Paddock by local authorities - and that she would likely have insights into what spawned such a terrible attack.
Google, which was running reports from 4chan in some of its search queries as a top story, explained to us what went wrong... and how it enabled some false information from one of the web's shadier corners to land as a top result.
Google said that 15 percent of searches that Google sees every day are new and that before the 4chan story broke there weren't many stories around the name "Geary Danley". "However, their removal was delayed, allowing them to be screen captured and circulated online. This should not have appeared for any queries, and we'll continue to make algorithmic improvements to prevent this from happening in the future", a spokesperson told Bloomberg.
"We are working to fix the issue that allowed this to happen in the first place and deeply regret the confusion this caused".
There were also several social media users who spread fake "missing friends" photos on Twitter, including the fake Twitter account Jack Sins, who shared a photo of a man claiming to be his missing father.
