This isn't quite the same subject as the OP, but maybe it's close enough.
Facebook has deleted 32 accounts that it has determined are fake accounts intended to disrupt the upcoming elections.
The accounts have not been decisively linked to the Russians, but the techniques are very similar to those used by the Russia-linked group, the Internet Research Agency, that has been indicted for its alleged interference during the 2016 elections.
There have been attempts to hack into the campaigns of several Democratic candidates:
In recent weeks, there have been reports of other meddling, including a Daily Beast report that the office of Claire McCaskill of Missouri, one of the Senate’s most vulnerable Democrats up for re-election this fall, was unsuccessfully targeted by Russian hackers last year, which Ms. McCaskill confirmed. American intelligence officials have indicated that at least one other unnamed Democratic senator up for re-election has been targeted.
But posts have also appeared supporting causes associated with the Left, probably in an attempt to encourage divisions and disruption:
Among the campaign’s efforts was organizing support for a counterprotest to a conservative rally. Specifically, an account called Resisters, which interacted with one Internet Research Agency account in 2017, created an Aug. 10 event, No Unite the Right 2 DC, to counter a planned white supremacist rally in Washington on Aug. 11 and 12 by the same group that organized the racist march in Charlottesville one year earlier.
(The counter protest is legitimate by the way, being organized by actual American activists. The point here is that these fake accounts appear to have a broad strategy to attempt to disrupt the elections.)
Also:
Activity was also detected around #AbolishICE, a left-wing campaign on social media that seeks to end the Immigration and Customs Enforcement agency.
The point is that
everyone should be skeptical of the "news" they get off their social media accounts, not only skeptical of the veracity of the information, but also who is actually disseminating the information and for what purpose. (In other words, be careful that you aren't being manipulated even if the information is true.)
