Facebook Inc. will not accept any new political advertisements in the week before the U.S. election, as part of broader efforts to encourage voting and "secure the integrity" of elections.

However, CEO Mark Zuckerberg wrote in a Sept. 3 Facebook post that during the final week before the Nov. 3 election, political and issue advertisers will be able to continue running ads that they began running before the final week and adjust the targeting for the ads.

Advertising revenue for Facebook, which accounts for the majority of its total revenue, was $18.32 billion in the second quarter, up 10% year over year from $16.62 billion in the same quarter of 2019.

In October 2019, Zuckerberg said ad money from politicians would make up less than 0.5% of Facebook's revenue in 2020. On a July 30 earnings call, Facebook CFO David Wehner said political ads are "just a small part of the overall advertising landscape even in election years."

The company also announced that it will remove posts that claim that people will get COVID-19 if they take part in voting. Facebook has committed to attaching a link to "authoritative information" about COVID-19 to posts that may use the pandemic to discourage voting.

The move comes as part of ongoing efforts to limit the influence of dangerous individuals, organizations and misinformation regarding voting on the platform.
