Who Sells Your Data
Data brokers are companies that collect everything they can about you and sell it to advertisers, researchers, and sometimes scammers.
Companies like Acxiom and Experian have files on most US adults — including kids whose parents shared photos online. AI now uses this data to target ads with scary precision.
Three things you can do
- Use opt-out forms (most brokers have one — required by some state laws)
- Use a credit freeze if worried about identity theft
- Avoid signing up for free apps that ask for too much info
Key terms in this lesson
The big idea: Data brokers know more about you than you would guess — and AI uses it to target you.
