Ask for your data, get your account nuked instead
A WIRED reporter spent a week filing data access requests with over 100 companies under the California Consumer Privacy Act. He explicitly asked them to send his data, not erase it. Instead, companies like Crunchbase and BeenVerified ignored the instructions and permanently deleted his accounts anyway. Crunchbase later blamed a human processing error, meaning customer support reps are apparently nuking accounts rather than dealing with the headache of data exports.
Compliance by total annihilation.
The backstory
The CCPA gives California residents the right to see exactly what large corporations are hoarding about them. But the corporate response process is so incredibly broken that asking for your file is often treated as a self destruct button.
