Twitter dropped an almost unfathomably large archive of tweets connected to two alleged influence campaigns on Wednesday. The trove included over 9 million tweets associated with 3,841 accounts connected to Russia’s notorious Internet Research Agency, or IRA, as well as more than a million tweets attributed to a network of 770 Iranian propaganda-pushing accounts. Twitter has never before released an archive of this size.
