On Monday, Facebook announced the changes to prevent its advertisement system to be affected by politically-driven bad actors, Bloomberg reported. The company also announced to hire more than 1000 employees next year to manually review the advertisements on Facebook ad network to support the U.S. government investigation into the Russian meddling in the 2016 election.

On Monday, Facebook also said that it shared the information about 3000 ads with congressional investigators. Last month, the company revealed the fake accounts used by Russians to buy ads and influence the last year presidential election.

The social giant said that Russia spent more than $100,000 on the advertisements.

Facebook will improve its machine learning technology

Facebook also said that it will invest and improve its machine learning technology, so it would automatically take down spam and malicious ads. The company also said that this new move would not only help Facebook review the content of ads but also reveal circumstances in which they were bought and their targeted audience, according to Forbes.

The social giant also said that it would bring more clearance and transparency to the company's ad campaign. The company is working to detect the patterns that could indicate potential meddling so that it would send those ads for manual operations.

People would be able to see the running ads on the page even if they are not a part of the targeted audience of that ad. The company added tight restrictions on choosing content for ads and forced buyers to mention their authenticity before purchasing.

Officials' statements

In September, Facebook founder and CEO Mark Zuckerberg published a video on his Facebook page, announcing to add 250 employees who would work on election integrity.

He also said that he did not want anyone to use the company's tool to undermine democracy. Twitter and Google have also started their separate investigations into the matter. Facebook, Twitter, and Google will attend the congressional hearings next month. Senate Select Committee and the House committee invited the companies.

Last week, Mark Warner, Virginia senator, said that the information provided by Facebook related to Russian bought ads was not sufficient. On Monday, a California Democrat and the U.S. Representative Adam Schiff said in a statement that " I am also committed to making all of these ads public as soon as possible."
