Block first, explain never
ZoomInfo CEO Blocks Researcher After Documenting Pre-Consent Biometric Tracking
CEO hits block; internet cries spying while marketers panic
TLDR: A researcher says ZoomInfo’s demo page tracks visitors before consent and got blocked by the CEO after posting proof. Comments split between calling it shady, shrugging “everyone does it,” and warning marketers about legal blowback—turning privacy, consent, and risk into the day’s hottest tech fight.
ZoomInfo’s big demo day turned into a LinkedIn soap opera when CEO Henry Schuck allegedly blocked a security researcher minutes after they posted evidence of pre-consent tracking on the GTM Studio landing page. Translation for normal humans: trackers were reportedly watching your mouse moves and typing patterns before you click “I agree.” The researcher claims 50+ tracking calls, biometrics toggled on, and a partner config pointing to Sardine.ai—prompting one commenter to call it “surveillance infrastructure.”
Cue the comments: SignalDr earns instant folk-hero status for the dramatic “blocked and dropping receipts” energy, while mike_d rolls eyes with a classic tech cynic take—“open DevTools on any site, film at 11.” jgalt212 goes full contrarian, arguing the legal risk is fading as Europe cools on GDPR (the EU privacy law), and asking why only Big Tech gets to push the line. Then superkuh drops a gloomy sermon: loading random scripts from everywhere is the web’s original sin—lock down your browser and stop feeding the beast.
Marketers in the thread clutch pearls: if this is real, could those “intent data” dashboards be built on shaky consent? The mood swings from CSI: Cookie Consent to LinkedIn Block Speedrun. No statement from ZoomInfo, lots of popcorn from the crowd, and one very loud message: privacy drama sells.
