Senator Maggie Hassan has put at least 35 data-broker firms—among them IQVIA Digital, Comscore, Telesign Corporation, 6sense Insights, and Findem—on notice following an investigation by The Markup, CalMatters, and WIRED that revealed these companies were using website code to hide their opt-out (data deletion) pages from search engines like Google, effectively erecting a barrier to consumer privacy under California law. The senator is demanding these firms explain their use of blocking code, commit to removing it by September 3, and provide audit reports to Congress. Advocates warn this tactic is a “dark pattern” that undermines individuals’ ability to reclaim personal information, with particularly grave implications for vulnerable groups such as survivors of domestic abuse. Meanwhile, efforts to regulate the data broker industry remain stalled despite widespread concern.

Key Takeaways
– Legal Pressure: Hassan’s inquiry demands accountability—firms must explain the hidden-page tactic and publicly disclose compliance efforts.
– Privacy Concerns: Concealing opt-out links is seen as a deceptive strategy that sabotages individual control over personal data, with risks compounding for those in unsafe situations.
– Regulatory Gap: Despite these revelations, broader federal action to regulate data brokers remains stalled, leaving a largely self-regulated industry intact.
In-Depth
It’s worth a quick pause to consider the foothold that data brokers have in our digital lives—and the subtle ways they can erode privacy while technically staying within the law. Senator Maggie Hassan recently stepped into the spotlight after an investigation revealed that 35 data-broker firms—including major players like IQVIA Digital, Comscore, 6sense, and Findem—were quietly hiding their opt-out or data-deletion pages from Google and other search engines.
That move, while technically legal, looks a lot like a “dark pattern”—an underhanded design tactic that makes it harder for people to exercise their rights. So Hassan is calling foul, demanding these firms explain their coding choices, remove the blockers by September 3, and turn over audit results to Congress.
It’s a fair ask: people ought to be able to find and use their privacy tools, not chase them. This issue isn’t abstract—it’s personal. For survivors of domestic abuse or stalking, hidden information means heightened risk. And yet, federal efforts to bump up oversight are nowhere to be found; even an earlier CFPB proposal to classify data brokers as consumer reporting agencies got quietly shelved. In essence, tell-and-fix letters like Hassan’s highlight a bigger truth: without enforceable standards, self-regulation in this space is minimal and consumers are left to fend for themselves behind a web of codes they can’t even see.
