Facebook has rolled out additional steps for improving the transparency of its advertisements after it learned 3,000 ads that ran during the 2016 election were tied to a Russian company.

"We care deeply about the integrity of elections around the world," Joel Kaplan, Facebook's vice president of global policy, said Monday. "We take responsibility for what happens on our platform and we will do everything we can [to] keep our community safe from interference."

Facebook said it will be changing its ads review system to pay more attention to both an ad's content and the "context in which it was bought and the intended audience." The company is adding 1,000 people to its global ads review team, and plans to invest more money in machine learning to assess when to flag ads and remove them from the site.

The company will also expand its restrictions on advertisers to prevent ads on the site "that use even more subtle expressions of violence." Currently, Facebook prohibits ads that promote the sale or use of weapons, direct threats, or include shocking content.

The company already announced new updates to its ad policies after it revealed last month that $100,000 in ad spending was tied to 3,000 ads traced back to 470 fake accounts. Facebook found the ads, which ran on the platform from 2015 to 2017, came from a Russian entity called the Internet Research Agency.

Following the revelations, Facebook said it is building a new tool to allow users to see other ads a page is running, including those not directly targeting a user. The social media platform is updating its policies to require advertisers who want to run election-related content to provide Facebook with more documentation, including the business or group they're representing.

Facebook and Twitter have come under scrutiny after it was discovered Russia used the platforms in an attempt to influence the 2016 election.

Facebook shared the ads purchased by the Internet Research Agency with Congress, and representatives from Facebook, Twitter and Alphabet, Google's parent company, were invited to testify publicly before the Senate Intelligence Committee on Nov. 1.
