An anonymous reader quotes a report from Recode: At least 1.4 million people on Twitter engaged with content created by Russian trolls during the 2016 presidential election, the company revealed on Wednesday. That's more than double the amount that Twitter initially identified -- and perhaps still just a fraction of the full universe of users who may have witnessed Kremlin propaganda over that period. In announcing the new data in a blog post, Twitter also said it had notified all 1.4 million affected users that they saw election disinformation. That fulfilled a pledge that the company previously made to members of Congress who are investigating Russia's tactics on social media. Notified users included those that followed one of the roughly 3,000 accounts belonging to the Internet Research Agency, the troll army tied to the Russian government, as well as users who retweeted, replied, liked or mentioned those IRA accounts in their tweets. But Twitter did not alert users who merely saw Russian troll tweets in their feeds but did not interact with the content. Nor did it reach out to users who saw tweets from the roughly 50,000 Russian bots that tweeted election-related content around November 2016.
