Political trolls adapt to deceive, confuse the public

- By Gianluca Stringhini and Savvas Zannettou The Conversati­on

Russian-sponsored Twitter trolls, who so aggressive­ly exploited social media to influence the 2016 U.S. presidenti­al election, didn't stop when Donald Trump was elected president.

Even after the election, they remained active and adapted their methods, including using images – among them, easyto-digest meme images such as Hillary Clinton appearing to run away from police – to spread their views. As part of our study to understand how these trolls operate, we analyzed 1.8 million images posted on Twitter by 3,600 accounts identified by Twitter itself as being part of Russian government-sponsored disinforma­tion campaigns, from before the 2016 election through 2018, when those accounts were shut down by Twitter.

While our study focused on those specific accounts, it's reasonable to assume that others exist and are still active. Until they were blocked by Twitter,

the accounts we studied were sharing images about events in Russia, Ukraine and the U.S. – including divisive political events like the “Unite the Right” rally in Charlottes­ville, Virginia, in August 2017. The images Russian government­backed trolls posted on Twitter appeared on other social networks, including Reddit, 4chan and Gab.

Changing focus

What they posted shifted over time. We analyzed the actual images themselves, to identify the topics of the posts, and even depictions of public figures and specific locations. In 2014, most of these accounts began posting images related to Russia and Ukraine, but gradually transition­ed to posting images about

U.S. politics, including material about Donald Trump, Hillary Clinton and Barack Obama.

This is consistent with some of our previous analysis of the text posts of these accounts, which showed they had changed their focus from Russian foreign policy to U.S. domestic issues.

Spreading their ideas, and others'

We found that the Russianbac­ked accounts were both creating new propaganda and amplifying messages created by others. About 30% of the images they tweeted had not appeared on other social media or elsewhere on Twitter and were therefore likely created by the Russians behind the accounts. The remaining 70% had appeared elsewhere.

By analyzing how their posts spread across different social networks over time, we were able to estimate how much influence these accounts had on the discussion­s on other online services like Reddit and Gab.

We found that the accounts' ability to spread political images varied by the social network. For instance, Russian-sponsored tweets about both parties were equally influentia­l on Twitter, but on Gab their influence was mainly on spreading images of Democratic politician­s. On Reddit, by contrast, the troll accounts were more influentia­l at spreading images about Republican politician­s.

Looking ahead

This research is an early step toward understand­ing how disinforma­tion campaigns use images. Our research provides a look at the past, but from what we have learned, we expect that informatio­n warriors will create more content themselves, and take advantage of material others create, to improve their strategies and effectiven­ess.

As the 2020 presidenti­al election approaches, Americans should remain aware that Russians and others are still continuing their increasing­ly sophistica­ted efforts to mislead, confuse and spread social discord in the public.
