In August 2019, when Facebook announced a few new features for advertisers such as ads in search, PI decided to take an in-depth look at what features the company offers its users when it comes to understanding its advertising practices. One of these features, which caught our attention is Facebook Ads Preference, a tool that among other things, lists businesses/advertisers that have uploaded your personal data to target you with (or exclude you from) ads on the platform.
