Introduction: In the digital age, the understanding that online activities are tracked has become commonplace. Users are familiar with seeing targeted ads and navigating through privacy settings that allow data sharing with numerous "partners." However, the true scale of this surveillance might be more staggering than most realize. A recent analysis by Consumer Reports delves into the world of Facebook, revealing the massive network of companies monitoring each user's online activity.
Scale of Surveillance: Consumer Reports conducted a unique study, utilizing a panel of 709 volunteers who shared archives of their Facebook data. The findings are eye-opening – a total of 186,892 companies sent data about these users to Facebook. On average, each participant had their data transmitted by a staggering 2,230 companies. Some participants experienced data-sharing with over 7,000 companies. This unprecedented study, facilitated by The Markup in recruiting participants, sheds light on server-to-server tracking, where personal data travels from companies' servers to Meta's servers.
Methodology: Participants downloaded a three-year archive of their Facebook data and provided it to Consumer Reports, enabling a closer look at normally hidden tracking methods. While acknowledging that the study's participants were a self-selected group, and therefore not demographically adjusted, Consumer Reports emphasizes that it doesn't claim representativeness of the entire U.S. population. The participants were likely more privacy-conscious and technically inclined, aligning with the audience of Consumers Reports.
Insights from Meta's Data: Despite limitations, the study provides a rare glimpse into the collection and aggregation of personal information online, directly from Meta. However, Consumer Reports identified issues with these tools, such as unclear identities of data providers and allowances for companies serving advertisers to ignore opt-out requests.
Key Players in Data Sharing: The study revealed that LiveRamp, a data broker based in San Francisco, appeared in 96% of participants' data, emphasizing its pervasive role. Notably, it's not just lesser-known data brokers involved; major retailers like Home Depot, Macy's, and Walmart ranked among the top 100 companies frequently sharing data. Credit reporting and consumer data companies, including Experian and TransUnion's Neustar, as well as popular platforms like Amazon, Etsy, and PayPal, were also prominent contributors.
Conclusion: As consumers navigate the intricate landscape of online privacy, the Consumer Reports study offers a rare, data-driven exploration into the extensive web of companies monitoring Facebook users. While Meta emphasizes transparency, the study underscores challenges in understanding and controlling data-sharing practices. This revelation prompts important conversations about the need for clearer privacy measures and a deeper understanding of how personal information is handled in the vast digital ecosystem.
