Twitter has published an archive of nearly 10 million tweets from troll accounts today, providing a vast pile of data for academics to pull from as they continue to research the methods foreign trolls used to influence public and political discourse across the world over the past few years.

The tweets originated between 2013 and 2018. Nine million of them were published by 3,800 different accounts affiliated with the Russian Internet Research Agency, and the last million tweets were posted by 770 accounts that the company said originated from Iran.
