The automated accounts were removed in September and October, according to Reuters.
Twitter has removed more than 10,000 accounts aiming to discourage people from voting in the US midterm elections on Tuesday, according to Reuters.
A Twitter representative confirmed to CNET that the social media site deleted automated accounts sharing misinformation, but couldn't confirm the 10,000 figure. The company removed the accounts in September and October, Reuters reported.
The accounts were reportedly made to look like they were from Democrats, but the party reported the tweets to Twitter. The accounts also appeared to be domestic. The Democratic Congressional Campaign Committee couldn't immediately be reached for comment.
"For the election this year we have established open lines of communication and direct, easy escalation paths for state election officials, DHS, and campaign organizations from both major parties," a Twitter representative said. "We removed a series of accounts for engaging in attempts to share disinformation in an automated fashion -- a violation of our policies. We stopped this quickly and at its source."
Twitter has been working to step up its fight against fake accounts. In July, it was reported that the social media company was suspending more than 1 million accounts a day in its battle against disinformation. In a June blog post, Twitter said it's "now removing 214 percent more accounts for violating our spam policies on a year-on-year basis." Twitter's efforts to combat bots and trolls come as it deals with revelations that Russian-linked social media troll accounts may have influenced the 2016 US presidential election.
