Mr. Mueller's indictment of a dozen Russians last month provided another thread, according to Facebook.
Special Counsel Robert Mueller is heading a sprawling investigation into possible collusion with Russian Federation by Trump's campaign to tip the vote toward the real estate tycoon.
Thirty events created by the inauthentic pages had already taken place, Facebook representatives said on the call, adding that the pages were taken down ahead of one event scheduled for August 10 in Washington, DC. The event had attracted 2,600 interested users, and 600 people said they would attend. They also organized about 30 events, only two of which were slated for the future.
However, it's still unclear whether the latest pages were directly tied to Russian Federation.
Facebook said it already shared the information about today's suspended accounts with U.S. law enforcement, Congress, other technology companies, and the Atlantic Council's Digital Forensic Research Lab, a research organization that helps Facebook identify and analyze abuse on its network. We believe this could be partly due to changes we've made over the previous year to make this kind of abuse much harder.
Among the techniques used to cover their trails were virtual private networks, and internet phone services. "And we've found evidence of some connections between these accounts and IRA accounts we disabled past year". The company has also announced new guidelines around political advertisements, requiring disclosure of who paid for them and keeping a database.
Facebook said it deleted pages such as Resisters after it found they violate a ban on coordinated inauthentic behavior. Among the most influential accounts nixed from the platform were "Aztlan Warriors", "Black Elevation", "Mindful Being", and "Resisters", according to Facebook.
Executives refused to say whether the suspicious accounts and pages primarily targeted Democratic or Republican voters, but several of the examples Facebook posted on its corporate website showed anti-Trump ads or those aimed at progressive causes. Additionally, the creators paid approximately $11,000 to run 150 ads on Facebook and Instagram. "The latest was created in May 2018", wrote Gleicher.
The first ad was created in April 2017; the last was created in June 2018.
It's unclear if anyone actually rocked up to one of those events.
Some of the content published Tuesday by Facebook was racially loaded, and some of it was anti-Trump.
The social media giant confirmed on its website on Tuesday that it has "removed 32 pages and accounts from Facebook and Instagram because they were involved in co-ordinated inauthentic behaviour".
Facebook, however, admitted in a blog post that it was in the "very early stages" of its investigation and didn't have "all the facts" about the newly discovered accounts.
Facebook said since the company has increased efforts to prevent abuse, the creators of fake accounts have begun to employ trickier, more secretive efforts.
They included an event called "No Unite the Right 2 - DC" that was meant to act as a counter-protest to a white nationalist gathering next month, and posts based around the hashtag #AbolishICE - a campaign to scrap the Immigration and Customs Enforcement agency over its controversial policy of separating children from their parents at the USA border. The indictment accused the IRA of seeking, in part, "to conduct what it called "information warfare against the United States of America" through fictitious U.S. personas on social media platforms and other Internet-based media". But security is not something that's ever done. "It's an arms race and we need to constantly improve too", it puffed itself up in one of the three posts on the issue.
Facebook said it had briefed USA law enforcement agencies, Congress and other tech companies about its findings.
