In effect, that's a simple measure of the impact that the IRA's accounts had. Twitter identified 1,062 additional accounts, bringing the total to 3,814; In the ten-week period before the 2016 election that the company studied, those IRA accounts posted 175,993 tweets. Only 8.4% were related to the upcoming elections, but that's still a wide impact that the Twitter platform unwittingly amplified.

Twitter also identified 13,512 more automated Russian-linked accounts that tweeted election-related material during the period, bringing that total to 50,258. In the company's blog post, it also reported better security techniques detected 60 percent more suspicious accounts last month than it did in October 2017. They're getting better at noticing automated activity, Twitter claims: Near-instant replies to tweets, too-regular Tweet timing and coordinated engagement are all red flags.

Twitter will invest more in machine-learning to spot and impede fake and automated accounts, the blog post stated. But popular multitasking overlay programs like Tweetdeck might suffer as the social media company may limit coordinated actions (known as "Tweetdecking") across multiple accounts "in Tweetdeck and via the Twitter API." To counter that, they promise to expand the developer onboarding process for those building atop the platform's API. (Twitter acquired Tweetdeck in 2011 and still runs it.)
