Facebook is going to begin banning false information involving voting ahead of the US’s midterm elections next month. It’s something the company has done before, but amid growing tensions with Congress and the public, these new rules are set to be tougher and more comprehensive than those prior.

Before the 2016 elections, Facebook banned posts that provided misinformation as to where people could go to vote and at what time polls opened or closed. But in today’s announcement, the Silicon Valley giant plans to push further, banning posts that advertise false voting methods, like sending a text to vote, or posts claiming primary votes will be counted in the general election.
