Election Day is a perfect environment for misinformation to spread, whether it’s through coordinated campaigns or honest error—or a mix of both. The stakes are high, there’s a lot of breaking news, and the US voting system isn’t always the most intuitive. Social media didn’t create misinformation, but as Emily Dreyfuss wrote last week, it can certainly add fuel to the fire. And the 2018 midterms have been, as the kids say, lit.

WIRED will update this page throughout Election Day to track the biggest stories, the most common hoaxes, and the likeliest sources of confusion as they emerge online. If you’re looking for ways to follow the election results tonight, Pia Ceres has you covered here. And most important of all, go vote!

Facebook Blocks More Accounts on the Eve of Elections

Late Monday night, Facebook announced it had identified dozens of accounts on Facebook and Instagram that “may be engaged in coordinated inauthentic behavior” after US law enforcement alerted the company to some online activity they believe might be linked to foreign entities. So far, the company says it has blocked around 30 Facebook accounts, whose associated pages were mostly in French and Russian, and 85 Instagram accounts, which were mostly in English and covered a mix of celebrities and politics. The company says it will investigate further.

“Typically, we would be further along with our analysis before announcing anything publicly,” Nathaniel Gleicher, Facebook’s head of cybersecurity policy, wrote in a post announcing the action. “But given that we are only one day away from important elections in the US, we wanted to let people know about the action we’ve taken and the facts as we know them today.” The news comes a little over a week after Facebook took down another coordinated network; that one, which the company said originated in Iran, appeared to follow the playbook Russian trolls perfected during the 2016 election: posing as US citizens to drive engagement around divisive social issues and national events.

As of Tuesday morning, the company had not identified any foreign entities connected to the blocked accounts. At 11:30 that evening, Facebook distributed a statement saying it blocked the accounts out of concern that the Russia-based Internet Research Agency was involved, but did not confirm whether that was actually the case. Additionally, Gleicher said, "a website claiming to be associated with the IRA published a list of Instagram accounts they claim to have created. We had already blocked most of these accounts yesterday and have now blocked the rest."
