On October 17, Twitter released an archive of over ten million tweets posted by accounts from 2013 through 2018. Of the total, over nine million tweets were attributable to 3,800 accounts affiliated with the Internet Research Agency, also known as Russia’s infamous St. Petersburg troll factory. Over one million tweets were attributable to 770 accounts, originating from Iran.

Each set is included in the same archive; however, because the actors and activity were separate, our analysis was conducted accordingly.
