Facebook blocks vote interferen­ce

- By Kelvin Chan

Facebook said it blocked 115 accounts for suspected “coordinate­d inauthenti­c behavior” linked to foreign groups attempting to interfere in Tuesday’s midterm elections.

The social media company shut down 30 Facebook accounts and 85 Instagram accounts and is investigat­ing them in more detail, it said in a blog post late Monday.

Facebook acted after being tipped off Sunday by federal law enforcemen­t officials. Authoritie­s notified the company about recently discovered online activity “they believe may be linked to foreign entities,” Facebook’s head of cybersecur­ity policy, Nathaniel Gleicher, wrote in the post.

Tech companies have stepped up their work against disinforma­tion campaigns, trying to stymie online troublemak­ers’ efforts to divide voters and discredit democracy. Facebook’s purge is part of countermea­sures to prevent abuses like those used by Russian groups two years ago to sway public opinion ahead of the 2016 presidenti­al election.

The Menlo Park company has been somewhat regularly disclosing such purges in recent months, most recently in October. More are

expected, because even as its systems get better at detecting and removing malicious accounts, the disinforma­tion campaigns are sharpening their attacks too.

Gleicher said Facebook will provide an update once it learns more, including whether the blocked accounts are linked to the Russian Internet Research Agency or other foreign entities.

Almost all of the Facebook pages associated with the blocked accounts appeared to be in French or Russian. The Instagram accounts were mostly in English and were focused either on celebritie­s or political debate. No further details were given about the accounts or suspicious activity.

Last month, Facebook removed 82 pages, accounts and groups tied to Iran and aimed at stirring up strife in the United States and Britain. It carried out an even broader sweep in August, removing 652 pages, groups and accounts linked to Russia and Iran.

Twitter, meanwhile, has said it has identified more than 4,600 accounts and 10 million tweets, mostly affiliated with the Internet Research Agency, which was linked to foreign meddling in U.S. elections, including the presidenti­al vote of 2016. The agency, a Russian troll farm, has been indicted by U.S. Special Counsel Robert Mueller for its actions during the 2016 vote.

Facebook, Twitter and other companies have been fighting misinforma­tion and election meddling on their services for the past two years . There are signs they’re making headway, although they’re still a very long way from winning the war.

Facebook, in particular, has reversed its stance of late 2016, when CEO Mark Zuckerberg dismissed as “pretty crazy” the notion that fake news on his service could have swayed the presidenti­al election.

In July, for instance, the company said that its spending on security and content moderation, coupled with other business shifts, would hinder its growth and profitabil­ity. Investors expressed their displeasur­e by knocking $119 billion off Facebook’s market value.

One problem is that it’s not just agents from Russia and other nations who are intent on sharing misinforma­tion and propaganda. There is plenty of homegrown fake news too, whether in the U.S. or elsewhere.

Still, Facebook is seeing some payoff, and not just with the accounts it has been able to find and take down. A recent research collaborat­ion between New York University and Stanford found that user “interactio­ns” with fake news stories on Facebook, which rose substantia­lly in 2016 during the presidenti­al campaign, fell significan­tly between the end of 2016 and July 2018. On Twitter, however, the sharing of such stories continued to rise over the past two years.
