1.5 Years of Fact-checks and Misinformation The Russo-Ukrainian War Reports

Due to Twitter/X dropping support for accademic research, the Fact-checking Observatory is currently unable to track the spread of recent fact-checks and misinformation on social media.

While we are investigating alternative data collection methods, the Fact-checking Observatory has stopped generating new reports.


Since November 2021, the observatory has generated more than 80 reports and tracked the spread of 6,228 fact-checks and misinforming content on social media relating to the Russo-Ukrainian war.
