14.4 Public Records, Data Brokers, and Exposure Basics
The Raw Rows Are Mostly Legal Records
A broker's cheapest inputs are public or quasi-public: corporate filings and registered-agent addresses, voter rolls with partial dates of birth, property deeds and assessor files, court dockets and judgments, professional licenses, and utility connection records. To those they bolt licensed mail data -- the change-of-address files that map your old address to your new one -- warranty and registration cards, loyalty lists, and the steady drip of breached databases. None of this is illegal to collect; the exposure is a legally constructed pipeline, which is why removal is procedural rather than a matter of outrage.
The Compilation Loop
Each cycle the broker ingests new files, normalizes names and addresses, and runs identity resolution to merge rows: name-plus-DOB clusters, household inference, children's ages guessed from shared surnames and birth years. Enrichment then attaches income band, home value, political and health-adjacent categories, each scored, and the deduplicated record is resold. Because registries and mail systems push monthly delta files, the loop regenerates whatever you deleted last month.
Downstream Multiplication
One compiled feed syndicates into dozens of people-search sites, most of them thin front-ends sharing the same backend databases. Deleting you from the visible site your name returns today does nothing for its siblings, and the row reappears from the upstream file within weeks. The broker file, not the website, is the choke point.
Opt-Out and Deletion Mechanics
Regimes differ. GDPR and CCPA-style rights grant access, deletion, and opt-out-of-sale requests against covered businesses, enforced with response deadlines. Most US brokers instead run voluntary web opt-out forms -- some requiring an email confirmation link, notarized form, or mailed request at the largest aggregators -- keyed to a suppression record ID. Submit whichever lever applies, log every confirmation, and re-verify on a schedule: suppressions expire, records regrow, and search-index suppression is a separate request from broker deletion.

Key Takeaways
- Most broker data begins as public or licensed-legal records: filings, voter rolls, deeds, court files, change-of-address mail.
- Identity resolution plus enrichment fuses those rows into scored profiles that regenerate each ingestion cycle.
- People-search sites are thin clones over shared backend feeds; deleting one visible site deletes nothing.
- GDPR and CCPA-style deletion rights cover some brokers; most US brokers rely on voluntary web or mailed opt-outs.
- Suppressions are keyed to record IDs and expire, so exposure checks must be recurring, not one-time.
