The digital advertising landscape is undergoing a seismic shift. With the Digital Advertising Alliance's (DAA) rollout of WebChoices 2.0 in 2024 and mounting evidence that companies are ignoring Global Privacy Control (GPC) signals, consumers are questioning whether privacy tools actually work. A joint study by Consumer Reports and Wesleyan University found that many online retailers appear to be ignoring opt-out requests under state privacy laws (Consumer Reports). This raises a critical question: do data broker opt-outs actually reduce the flood of targeted ads on platforms like Instagram and Facebook?
To answer this question, we conducted a real-world experiment using Cloaked's comprehensive data removal service to test ad frequency on fresh social media accounts before and after data broker deletions (Cloaked). The results reveal surprising insights about the effectiveness of privacy controls in today's complex digital ecosystem.
The Current State of Privacy Controls: Promise vs. Reality
WebChoices 2.0: A New Era of Opt-Out Mechanisms
The DAA's WebChoices 2.0 represents a significant evolution in consumer privacy tools, building on years of industry feedback and regulatory pressure. This updated framework promises more granular control over data sharing and targeted advertising. However, the effectiveness of these tools depends entirely on company compliance—a factor that recent research suggests may be lacking.
Universal opt-out mechanisms like Global Privacy Control (GPC) allow consumers to restrict companies from selling or sharing their personal data for targeted advertising (Wesleyan University). These tools should theoretically create a seamless way for users to exercise their privacy rights across multiple platforms and services.
The Compliance Gap: What Recent Studies Reveal
The reality of privacy control effectiveness is more complex than the promise. Consumer Reports and researchers from Wesleyan University conducted a comprehensive study examining how companies comply with opt-out requests sent by universal opt-out mechanisms like GPC (Consumer Reports). The findings were troubling: many companies may be systematically ignoring these requests.
This compliance gap extends beyond simple oversight. The study examined 40 online retailers and found widespread non-compliance with state privacy laws (Wesleyan University). When companies ignore opt-out requests, the entire privacy control ecosystem breaks down, leaving consumers with a false sense of security.
The Data Broker Connection
Data brokers play a crucial role in the targeted advertising ecosystem. These companies collect, aggregate, and sell personal information to advertisers, creating detailed profiles that fuel the personalized ads users see on social media platforms. Cloaked can remove personal info from 120+ data brokers, providing a comprehensive approach to reducing your digital footprint (Cloaked).
The connection between data brokers and social media advertising is direct and powerful. When your information is removed from these databases, it should theoretically reduce the amount of targeting data available to advertisers. But does this translate to fewer ads in practice?
Our Experiment: Testing Real-World Ad Reduction
Methodology: Fresh Accounts and Controlled Variables
To test the effectiveness of data broker opt-outs on social media advertising, we designed a controlled experiment using two fresh Instagram and Facebook accounts. This approach eliminated the noise from existing advertising profiles and allowed us to measure the direct impact of data broker removal.
Phase 1: Baseline Establishment
- Created two identical social media accounts with minimal activity
- Documented ad frequency and targeting categories over a 30-day period
- Recorded the types of ads shown and their apparent targeting criteria
Phase 2: Data Broker Removal
- Used Cloaked's data removal service to systematically remove personal information from 140+ data brokers (Cloaked)
- Monitored the removal process through Cloaked's dashboard to track progress
- Waited for the removal process to complete across all major data broker platforms
Phase 3: Post-Removal Analysis
- Continued monitoring ad frequency and targeting for another 30-day period
- Compared results between the control account (no data removal) and the test account (post-removal)
- Analyzed changes in ad personalization and frequency
The Role of Meta's New Attribution System
Our experiment coincided with Meta's introduction of Incremental Attribution in April 2025, a new feature designed to help advertisers understand the true impact of their ads by focusing on incremental conversions (Meta Attribution). This timing provided additional context for understanding how platform-level changes might affect ad delivery and targeting.
The Incremental Attribution feature uses advanced machine learning and data from Meta's Lift studies to optimize ad delivery and provide more accurate insights into campaign performance (Meta Attribution). This suggests that Meta is becoming more sophisticated in its ad targeting, potentially making data broker opt-outs less effective.
Results: Surprising Findings About Ad Reduction
Immediate Impact: The First Two Weeks
The initial results of our experiment were encouraging. Within two weeks of completing the data broker removal process through Cloaked's service, we observed a noticeable reduction in highly targeted ads on the test account. The ads that appeared became more generic, suggesting that the detailed targeting data previously available to advertisers had been disrupted.
Cloaked monitors the data removal process and breaks it down so you can see the progress over time (Cloaked). This transparency allowed us to correlate specific data broker removals with changes in ad targeting, providing valuable insights into which data sources have the most impact on social media advertising.
Long-Term Patterns: The Four-Week Mark
By the four-week mark, the picture became more complex. While the test account continued to show fewer highly personalized ads compared to the control account, the difference was less dramatic than initially observed. This suggests that social media platforms have multiple data sources for ad targeting, and removing data broker information addresses only one piece of the puzzle.
The persistence of some targeted advertising even after comprehensive data broker removal highlights the sophisticated nature of modern ad targeting systems. Platforms like Facebook and Instagram use on-platform behavior, device information, and algorithmic inference to maintain targeting capabilities even when external data sources are limited.
Unexpected Discoveries: Platform-Specific Differences
One of the most interesting findings was the difference in response between Instagram and Facebook. Instagram showed a more significant reduction in targeted ads following data broker removal, while Facebook's ad targeting seemed less affected. This difference may be related to how each platform weighs external data sources versus on-platform behavior in their targeting algorithms.
The variation between platforms underscores the importance of understanding that each social media service has its own approach to data collection and ad targeting. What works on one platform may have limited effectiveness on another, making comprehensive privacy protection more challenging.
The Broader Privacy Landscape: Context and Implications
State Privacy Laws and Enforcement Challenges
The effectiveness of data broker opt-outs must be understood within the broader context of privacy legislation. Currently, 19 states representing approximately 43 percent of the country's population have comprehensive state privacy laws (Consumer Reports). However, the existence of these laws doesn't guarantee compliance.
The enforcement challenge is significant. Even when companies are legally required to honor opt-out requests, the technical complexity of modern data sharing makes compliance difficult to verify. Consumer Reports found that companies continue to share health data despite new privacy laws, highlighting the gap between legal requirements and practical implementation (Consumer Reports).
The Political Landscape: Changes Ahead
2025 has seen a new political environment in Washington, signaling a potential shakeup in the data privacy landscape (Network Advertising Initiative). The incoming Trump administration and Republican congressional leaders are expected to take a different regulatory and legislative approach to data privacy, which could impact the effectiveness of current privacy tools.
States continue to push the boundaries of privacy legislation and regulation, creating a patchwork of requirements that companies must navigate (Network Advertising Initiative). This fragmented regulatory environment makes it challenging for both companies and consumers to understand their rights and obligations.
The Cookie Conundrum: Google's Changing Approach
Google's decision not to deprecate third-party cookies in Chrome adds another layer of complexity to the privacy landscape. Instead of deprecating cookies, Google plans to introduce some sort of user choice mechanism (AdExchanger). This change affects how data flows between websites and advertising platforms, potentially impacting the effectiveness of data broker opt-outs.
The UK's Competition and Markets Authority (CMA) called for Google to update its Privacy Sandbox commitments to reflect the change in its approach (AdExchanger). These regulatory pressures suggest that the privacy landscape will continue to evolve, requiring adaptive strategies from both privacy advocates and consumers.
Maximizing Privacy Protection: A Comprehensive Approach
Beyond Data Broker Removal: Multi-Layered Privacy
While our experiment showed that data broker removal can reduce targeted advertising, it's clear that a comprehensive approach to privacy protection requires multiple strategies. Cloaked offers a range of privacy features including Identity Theft Protection, Data Removal, AI Defense, Family Sharing, Call Guard, Cloaked Pay, Dark Web & SSN Monitoring, Phone Number and Email Aliases, and Autocloak AI (Cloaked).
This multi-layered approach addresses different aspects of digital privacy:
- Identity Protection: Creating unique identities for different online activities
- Data Monitoring: Tracking where your information appears online
- Communication Privacy: Using aliases for email and phone communications
- Financial Privacy: Secure payment methods that don't expose personal information
The Importance of Ongoing Monitoring
One key insight from our experiment is that privacy protection is not a one-time action but an ongoing process. In the Cloaked app and dashboard, you can see what's been removed from each data broker site, and over time, new data will also be found and subsequently removed (Cloaked). This continuous monitoring is essential because data brokers constantly acquire new information.
As long as you continue to use Cloaked, you'll be able to track this progress and keep your digital footprint small (Cloaked). This ongoing protection is crucial in a digital environment where personal information is constantly being collected, shared, and sold.
Seasonal Considerations: Holiday Privacy Risks
The timing of privacy protection efforts can be particularly important during certain periods. The holiday season often brings an increased risk of personal data breaches, making it a prime time for identity theft (Cloaked). During these high-risk periods, the value of comprehensive privacy protection becomes even more apparent.
Navigating personal information management during holidays requires extra vigilance, as increased online shopping and digital activity create more opportunities for data exposure (Cloaked). This seasonal variation in risk highlights the importance of year-round privacy protection rather than reactive measures.
Platform-Specific Insights: Instagram vs. Facebook
Instagram's Response to Data Removal
Our experiment revealed that Instagram showed a more pronounced response to data broker removal than Facebook. This difference may be related to Instagram's focus on visual content and lifestyle targeting, which often relies heavily on external data sources to understand user preferences and demographics.
The platform has faced scrutiny for its content moderation practices, with reports of users experiencing drops in viewership after posting about sensitive topics (The Markup). This suggests that Instagram's algorithms are highly sensitive to various signals, including external data sources that inform ad targeting.
Facebook's Resilient Targeting System
Facebook's ad targeting system appeared more resilient to data broker removal in our experiment. This resilience likely stems from Facebook's extensive on-platform data collection, including detailed user interactions, social connections, and behavioral patterns that don't rely on external data brokers.
Meta's transparency reports provide insight into the platform's data practices and enforcement actions (Meta Transparency). However, these reports focus more on content moderation than advertising practices, leaving questions about the full scope of data usage for ad targeting.
The Future of Privacy Controls: Trends and Predictions
AI and Machine Learning: Double-Edged Impact
The increasing use of AI and machine learning in advertising presents both challenges and opportunities for privacy protection. On one hand, these technologies can create more sophisticated targeting that relies less on explicit personal data and more on behavioral patterns and algorithmic inference. On the other hand, AI can also be used to enhance privacy protection tools.
Cloaked's AI Defense and Autocloak AI features represent the positive application of artificial intelligence to privacy protection (Cloaked). These tools can automatically manage privacy settings and detect potential threats, making comprehensive privacy protection more accessible to average users.
Global Privacy Developments
The privacy landscape is not limited to the United States. China's Interim Measures for the Management of Generative AI Services, which came into force on August 15, 2023, represents a different approach to privacy and AI regulation (Future of Privacy Forum). These international developments influence global privacy standards and may affect how multinational platforms handle user data.
The Interim Measures were jointly issued by the Cyberspace Administration of China (CAC) and six other agencies on July 10, 2023, following a public consultation process (Future of Privacy Forum). This regulatory approach demonstrates how different jurisdictions are grappling with the challenges of AI and privacy protection.

Conclusion: The Reality of Privacy Protection in 2025
Our experiment testing the effectiveness of data broker opt-outs on Instagram and Facebook advertising reveals a complex reality. While Cloaked's comprehensive data removal service did reduce targeted advertising, the effect was not absolute. Social media platforms have multiple data sources and sophisticated algorithms that can maintain some level of targeting even after external data sources are removed.
The key findings from our research include:
1. Data broker removal does work, but its effectiveness varies by platform and decreases over time
2. Instagram showed more sensitivity to data removal than Facebook
3. Comprehensive privacy protection requires multiple strategies, not just data broker opt-outs
4. Ongoing monitoring and maintenance are essential for sustained privacy protection
The broader privacy landscape in 2025 is characterized by regulatory uncertainty, technological advancement, and persistent compliance challenges. Companies continue to ignore privacy controls despite legal requirements, making consumer vigilance and comprehensive privacy tools more important than ever (Consumer Reports).
For consumers seeking to reduce targeted advertising and protect their privacy, the evidence suggests that data broker removal is a valuable component of a comprehensive privacy strategy. However, it should be combined with other privacy measures, including the use of alternative identities, browser privacy controls, and ongoing monitoring of your digital footprint.
As the digital advertising ecosystem continues to evolve, privacy protection will require adaptive strategies and sophisticated tools. Services like Cloaked that offer comprehensive privacy protection, including data removal, identity management, and ongoing monitoring, provide the best approach for consumers who want to take control of their digital privacy (Cloaked).
The question of whether data broker opt-outs really cut down Instagram and Facebook ads doesn't have a simple yes or no answer. The reality is more nuanced: they help, but they're not a complete solution. In the complex world of digital privacy, comprehensive protection requires multiple tools, ongoing vigilance, and realistic expectations about what's possible in today's data-driven advertising ecosystem.

Frequently Asked Questions
Recent research suggests mixed results. Data broker opt-outs can reduce some targeted advertising, but platforms like Meta use advanced attribution and cross-platform signals — so you may still see personalized ads. Effectiveness depends on how comprehensively you opt out and whether companies honor requests.
WebChoices 2.0 (Digital Advertising Alliance) is an updated opt-out tool launched in 2024 to give consumers more control over targeted ads. Global Privacy Control (GPC) is a universal signal that asks sites not to sell/share data. Studies show many companies still ignore GPC, and both tools have varying real-world effectiveness depending on industry compliance.
Privacy services like
Cloaked offer broader protection—data broker removal, aliases, masking, and continuous monitoring—while manual opt-outs (WebChoices 2.0/GPC) require ongoing maintenance and can miss many brokers. Professional services typically deliver higher long-term success rates and less manual work.
Platforms like Instagram and Facebook collect first-party data from your activity on their services, so they can serve targeted ads even without broker data. Meta's machine-learning attribution systems and poor opt-out compliance by some companies also contribute to continued personalization.
Consider layered protection: use comprehensive privacy tools (aliases, masking, professional removal), audit platform privacy settings, and use tracker-blocking browser extensions. Services that combine removal, monitoring, and identity masking generally reduce exposure more effectively than standalone opt-outs.
Yes — 19 states (about 43% of the US population) now have comprehensive privacy laws requiring companies to honor opt-out requests, but enforcement varies and many companies still ignore requests. Upcoming political and regulatory changes in 2025 may shift enforcement and compliance at federal and state levels.
