The Facebook Ads Library contains data on all ads related to social issues, elections or politics, and you can find out 'how ads were shown' and 'who did.' Is possible. A research team from Laura Edelson of the New York University Tandon School of Engineering and others conducted a survey on the Facebook ad library for data on ads posted from May 2018 to June 2019.

Many of these political advertisements do not know who the advertiser is on the Facebook ad library, even though the advertiser is required to disclose his / her identity in the Facebook ad library. , It became clear that the advertiser was advertising politically, cleverly evading the identity. The research team estimates that the advertising costs paid by these fraudulent advertisers will total about $ 37 million (about 3.8 billion yen).

The research team has questioned that the information provided is unreliable and it is difficult to know who is behind an ad campaign from the Facebook ad library.

'' Was.

Facebook says, 'Because of this survey, Facebook's ad approvals and transparency have changed significantly.' 'Facebook is more transparent to political advertising than TV, radio and other digital advertising platforms.' A statement has been issued. According to the Washington Post's report, Facebook has provided information about the identity of the advertiser, such as tax ID, to Facebook pages that run political advertisements since October 2019 after the survey.

Edelson admits that `` Facebook's shift in political advertising will increase the transparency of advertising, '' but said, `` If Facebook is not constantly vigilant, protect voters from manipulation by malicious advertisers. Facebook's effort will not work. '
