SignalDr··on ZoomInfo CEO blocks researcher after documenting pre-consent biometric tracking
Considering that sales/marketing are basically the only business functions that have never been held to a compliance standard, they're betting it never comes.
SignalDr··on ZoomInfo CEO blocks researcher after documenting pre-consent biometric tracking
I just got blocked by the CEO of ZoomInfo for documenting surveillance infrastructure on their GTM Studio landing page.

Timeline: 1. CEO posts product demo on LinkedIn 2. I analyze the landing page with Chrome DevTools 3. I post findings in comments (40+ cookies pre-consent, biometrics, etc.) 4. CEO blocks me within minutes

So I'm releasing the full evidence pack publicly: https://github.com/clark-prog/blackout-public

What I found: - Sardine.ai behavioral biometrics (mouse/typing patterns) firing before consent - PerimeterX device fingerprinting pre-consent - 118 unique tracking domains on a single page load - Base64-encoded config showing "enableBiometrics: true" - Formal partnership with Sardine (partnerId: "zoominfo")

The irony: ZoomInfo sells visitor identification tools but uses 3 external fingerprinting vendors on their own site.

All evidence is reproducible. HAR files, deobfuscated code, legal analysis included.

AMA about findings or methodology.
