A U.S. Senate investigation has uncovered that major data brokers-including Comscore, IQVIA Digital, Telesign, and 6sense Insights-used code to block search engines from indexing their opt-out pages. This made it nearly impossible for consumers to find ways to stop the sale of their personal data.
The practice was exposed after pressure from Senator Maggie Hassan, leading four companies to remove the blocking code. One firm, Findem, still retains the restriction, citing a missed email from the senator’s office.
These opt-out pages are not optional; they are legally required in many states. Hiding them undermines consumer rights and increases vulnerability to identity theft and scams.
Despite progress, the broader system remains unregulated. Without a federal privacy law, individuals must manually track down and submit requests to dozens of firms.
The issue highlights a fundamental imbalance: companies profit from personal data while making control difficult. Transparency should not depend on congressional scrutiny.
