Policy

  • Universal Digital Ad Transparency

    Many of the largest social media platforms – Facebook, Google, Snapchat, and Twitter – maintain some form of public ad archive. However many of these archives are incomplete, poorly implemented, hard to access by researchers and have very different formats and modes of access. A group of 15 researchers proposes new standard for universal ad disclosure that should be met by every platform that publishes digital ads.

  • Public Support for Ad Observer

    In October 2020, more than 80 research, journalism, civic tech, privacy organizations and individuals signed a call to Facebook's CEO Mark Zuckerberg to retract a cease and desist order against NYU researchers' Ad Observer plug-in tool, which allows Facebook users to volunteer to contribute information about the ads and ad targeting they encounter on the platform. Facebook also demanded that the project delete all the data it has collected. This issue remains ongoing.
