FoxNews.com - Facebook uncovered "sophisticated" efforts, possibly linked to Russia, to influence American politics in advance of the U.S. midterm elections.
The company said in a blog post that it removed 32 accounts from Facebook and Instagram because they were involved in "coordinated" political behavior and appeared to be fake.
Facebook did not explicitly say that the effort was aimed at influencing the midterm elections in November, but the timing of the suspicious activity would be consistent with such an attempt.
The company, which said it is in the early stages of its investigation, held briefings in the House and Senate this week.
The company said it doesn't know who is behind the efforts, but said there may be connections to Russia. Facebook said it has found some connections between the accounts it removed and the accounts connected to Russia's Internet Research Agency that it removed before and after the 2016 U.S. presidential elections.
U.S. Senator Mark Warner, D-Va., who introduced the Honest Ads Act earlier this year to help prevent foreign interference in U.S. elections, praised Facebook's elections.
“Today’s disclosure is further evidence that the Kremlin continues to exploit platforms like Facebook to sow division and spread disinformation, and I am glad that Facebook is taking some steps to pinpoint and address this activity," Warner said in a statement to Fox News.
"I also expect Facebook, along with other platform companies, will continue to identify Russian troll activity and to work with Congress on updating our laws to better protect our democracy in the future,” he continued.
"It’s clear that whoever set up these accounts went to much greater lengths to obscure their true identities than the Russian-based Internet Research Agency (IRA) has in the past," the company said in its statement. "We believe this could be partly due to changes we’ve made over the last year to make this kind of abuse much harder."
The earliest page was created in March 2017. Facebook says more than 290,000 accounts followed at least one of the fake pages. The most followed Facebook Pages had names such as "Aztlan Warriors," ''Black Elevation," ''Mindful Being," and "Resisters."
Facebook says the pages ran about 150 ads for $11,000 on Facebook and Instagram, paid for in U.S. and Canadian dollars. The first ad was created in April 2017; the last was created in June 2018.
The perpetrators used virtual private networks and internet phone services, and paid third parties to run ads on their behalf, according to Facebook.
