A team of researchers at the University of Adelaide have found that as many as 80 percent of tweets about the 2022 Russia-Ukraine invasion in its early weeks were part of a covert propaganda campaign originating from automated fake ‘bot’ accounts.

An anti-Russia propaganda campaign originating from a ‘bot army’ of fake automated Twitter accounts flooded the internet at the start of the war. The research shows of the more than 5-million tweets studied, 90.2 percent of all tweets (both bot and non-bot) came from accounts that were pro-Ukraine, with fewer than 7 percent of the accounts being classed as pro-Russian.
