CAPTCHAs don't prove you're human – they prove you're American
CAPTCHAs were designed to tell humans from automated scripts, but recent analysis shows they now function more as a filter for American users. By presenting challenges that align with U.S.-centric language and cultural references, these tests often block non‑American visitors, turning a security tool into a de facto nationality check. The shift raises concerns about accessibility and bias in online verification.
