Overall, though, Twitter says it saw far less foreign "platform manipulation" than around the 2016 election. It suspended 418 accounts that seemed to have ties to Russia's notorious Internet Research Agency -- in the fall, Twitter said it previously kiboshed 3,843 accounts it suspected were linked to the agency. Before Election Day, it also culled "764 accounts engaged in malicious automation located in Venezuela, some of which tweeted about the 2018 US midterm election."

Notably, Twitter and Facebook worked together to snuff out organized disinformation efforts. Facebook revealed Thursday it had taken down 783 accounts, pages and groups across Facebook and Instagram that exhibited "coordinated inauthentic behavior [...] directed from Iran."

"We're actually able to move more quickly and remove these larger networks," Facebook's cybersecurity policy chief Nathaniel Gleicher told the Financial Times. "It's an encouraging example of the type of collaboration we're hoping to build across industry." He also noted the companies are sharing notes on fake news campaigns earlier than they used to.
