Twitter is releasing all the accounts and related content associated with potential information operations that we have found on our service since 2016. We had previously disclosed these activities, but are now releasing substantially more information about them to enable independent academic research and investigation. These large datasets comprise 3,841* accounts, originating in Russia, and 770 other accounts, potentially originating in Iran. They include more than 10 million Tweets and more than 2 million images, GIFs, videos, and Periscope broadcasts.”]
