On their website, you can consult multiple documents and studies on this subject, from how social bots work to the potential for detecting fake news using blockchain.
Their working paper, “Troops, Trolls and Troublemakers: A Global Inventory of Organized Social Media Manipulation,” describes, for example, how “cyber troops” operate in 28 countries where they have identified organizations created specifically for the manipulation of public opinion, most of which, they claim, are financed with public money. They warn: “Authoritarian regimes are not the only ones, not even the best, that manipulate social media in an organized manner.”
Also interesting is his report, "Computational Propaganda telegram data Worldwide," which analyzes how social media has been or is being used to manipulate public opinion in nine specific countries: the United States, China, Russia, Poland, Brazil, Canada, Germany, Ukraine, and Taiwan.
This is a project led by the European Union's anti-hoax and disinformation unit, the European External Action Service East Stratcom Task Force, to identify and respond to disinformation campaigns, specifically those promoted by the Kremlin .
Since September 2015, they have analyzed 3,500 cases of disinformation , all of which are collected in the website's public database : you can search by topic, date, keyword, and language.
For example, if you search for "Catalonia," you can find dozens of cases of misinformation or fake news, such as the claim that the Balearic Islands are also demanding independence from Spain, published in September by Sputnik, or that Europeans invented the theory of global separatism.
