Facebook looking at behavior to weed out fake accounts

San Francisco, Apr 13: Facebook has said it has started weeding out bogus accounts by watching for suspicious behavior such as repetitive posts or torrents of messages.

The security improvement was described as being part of a broader effort to rid the leading social network of hoaxes, misinformation, and fake news by making sure people are who they claim to be.

"We've found that when people represent themselves on Facebook the same way they do in real life, they act responsibly," Shabnam Shaik of the Facebook protect and care team said in a blog post.

"Fake accounts don't follow this pattern, and are closely related to the creation and spread of spam." Accounts suspected of being bogus are suspended and holders asked to verify identifies, which scammers typically don't do, according to the California-based social network.

In France, the new tactic has already resulted in Facebook taking action against 30,000 accounts believed to be fakes, Shaik said. "We've made improvements to recognize these inauthentic accounts more easily by identifying patterns of activity -- without assessing the content itself," Shaik said.

"With these changes, we expect we will also reduce the spread of material generated through inauthentic activity, including spam, misinformation, or other deceptive content that is often shared by creators of fake accounts."

Under pressure to stymie the spread of fake news, Facebook has taken a series of steps including making it easier to report such posts and harder to make money from them.

Facebook also modified its displays of trending topics to find stories faster, capture a broader range of news, and help ensure that trends reflect real world events being covered by multiple news outlets.

Facebook chief Mark Zuckerberg has sought to deflect criticism that the huge social network may have been used to fuel the spread of misinformation that affected the 2016 US presidential race.

Facebook last week unleashed a new weapon in the war against "revenge porn" at the social network as well as the messaging services Messenger and Instagram. When intimate images shared on Facebook without permission are reported, confirmed and removed, the company will use photo-matching technology to prevent copies from being shared again on its platform.
