The mechanism
How the broker economy works
Nobody signs up to be profiled. The data arrives anyway — from places you did business, forms you filled out, and code running silently inside apps you installed for something else.
The industry runs in three moves: collect from many sources, aggregate those scraps into a single profile keyed to your name and address, and sell access to that profile on the open market. The same record can be resold hundreds of times, and brokers buy from each other, so a single data point spreads far past wherever it started.
Why we cover this
The broker loophole is a warrant the government never has to ask for.
This page is the companion to the third-party doctrine. That page explains why data you hand a company loses Fourth Amendment protection; brokers are what happens next. Because the records are for sale, an agency that would need a warrant to demand your data can often just buy it instead — and the same market is open to a landlord, an abuser, or anyone with a grudge and a credit card.
The lever that already exists
One request, every broker: California’s DELETE Act
The usual advice is to opt out of hundreds of brokers one form at a time. One state built a shortcut — a single request that every registered broker has to honor — and it’s the clearest “close the loophole” win on the board.
The idea: instead of chasing brokers individually, you file once through a state-run platform, and every data broker registered in that state must delete what they hold on you and stop selling it. It ties directly into our Privacy by State map — a handful of states run broker registries at all, and most run none.
State broker registries
Where a broker registry exists at all, you at least have a list to work from. Confirm each before publishing.
California
[Research: confirm the registry, the administering agency, and the DELETE Act deletion mechanism. Link the official registry page.]
Vermont
[Research: confirm Vermont’s data-broker registration law and link the state registry.]
Texas
[Research: confirm Texas’s broker registration requirement and link the registry.]
Oregon
[Research: confirm Oregon’s broker registration law and link the registry.]
Add or drop states as the research turns up. Do not assert a state has a registry until the official page is located and linked.
Getting out
Two ways to claw your data back
You can do the removals yourself, or pay someone to do them on repeat. We lean hard toward the first — and we’re candid about the trade-offs of the second.
Free, and you keep the receipts
The bottleneck was never difficulty — it was knowing which brokers exist and where each opt-out lives. Community-maintained directories solve exactly that: a running list of brokers with a direct link to each removal form.
Read the fine print first
Removal services promise to do the opt-outs for you, forever, for a subscription. The structural problem: broker profiles regenerate, so you’re renting a fix to a problem that keeps coming back — and some of these companies sit uncomfortably close to the data business they claim to fight.
A warning that generalizes
When the tool protecting you gets bought
A privacy product is only as durable as its ownership. The guarantees you signed up for can change hands overnight — and a removal service holds a detailed list of exactly the data you most wanted gone.
