Facebook said Monday it blocked some 30 accounts on its platform and 85 more on Instagram after police warned they may be linked to "foreign entities" trying to interfere in the United States midterm election.
The social network has revealed that these accounts could be linked to "foreign entities" and this suggest that they could be use to interfere with the elections.
"We have immediately blocked these accounts and are in the process of investigating them in more detail", adds Facebook. Some of the Instagram accounts "were focused on celebrities" and others on "political debate", it said.
USA officials say there is no indication that America's voting infrastructures have been compromised but they warn that foreign operatives are trying to influence voters.
He also pledged to keep the public updated, suggesting Facebook may move to block more suspicious accounts.
Facebook has disrupted a disinformation campaign targeting the USA midterm elections first detected by American law enforcement.
"At this time we have no indication of compromise of our nation's election infrastructure that would prevent voting, change vote counts, or disrupt the ability to tally votes", the statement said adding "Americans should be aware that foreign actors-and Russian Federation in particular-continue to try to influence public sentiment and voter perceptions through actions meant to sow discord".
Earlier on Monday, numerous federal agencies, including the FBI, wrote a joint statement alerting Americans to the fact that "foreign actors-and Russian Federation in particular-continue to try to influence public sentiment and voter perceptions through actions meant to sow discord".
In an announcement late Monday, Nathaniel Gleicher, Facebook's head of cybersecurity policy, said the social media giant has so far identified 115 total accounts on Facebook and Instagram that "may be linked to foreign entities".
"Typically, we would be further along with our analysis before announcing anything publicly", he said. The statement detailed government efforts to prevent election interference.
Twitter said Saturday it deleted a "series of accounts" that attempted to share disinformation.
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.
