Goal of Russian ads was sowing discord and not support for any particular candidate

The anti-Trumpers' promising story-line -- "Trump and Russia colluded on Facebook" -- had to be downgraded to merely "Russia sought to create incivility and chaos" when it was discovered that the Russia-linked group in question promoted issues and groups on both sides of the political spectrum.

According to Facebook's investigators, the company sold up to $150,000 worth of ads to a Russian government-affiliated troll farm known as the Internet Research Agency, which bought the ads through hundreds of phony Facebook pages and accounts.

At least one of the over 3,000 Russia-bought ads, which Facebook will soon turn over to Congress, promoted Black Lives Matter and specifically targeted audiences in Ferguson, Missouri, and Baltimore, CNN reported on Wednesday.

The Black Lives Matter ad appeared on Facebook at some point in late 2015 or early 2016, the sources said. The sources said it appears the ad was meant to appear both as supporting Black Lives Matter but also could be seen as portraying the group as threatening to some residents of Baltimore and Ferguson.

New descriptions of the Russian-bought ads shared with CNN suggest that the apparent goal of the Russian buyers was to amplify political discord and fuel an atmosphere of incivility and chaos, though not necessarily to promote one candidate or cause over another. Facebook's review of Russian efforts on its platform focused on a timeframe from June 2015 to May 2017.

These ranged from posts promoting Black Lives Matter to posts promoting gun rights and the Second Amendment to posts warning about what they said was the threat undocumented immigrants posed to American democracy. Beyond the election, Russians have sought to raise questions about western democracies.

According to the Washington Post, other ads showed support for Democratic presidential candidate Hillary Clinton among Muslim women.

I came to the same conclusion about the Russians when they used intermediaries to set a meeting with Dongal Trump, Jr. which was supposed to dish dirt on Hillary Clinton.  Those at the meeting had ties to the dirty dossier on Trump which was also tied to Russian sources.  They were clearly trying to create discord and distrust and with the media and the Democrats, they were screamingly successful.
