CAPTCHAs Are a Timing Vulnerability

The agent transcript shows CAPTCHAs slow down autonomous agents but don't stop them — agents can iterate, automate image solving attempts, exploit token expiry windows, and chain account‑creation steps until a site token or session timing is favorable. Defenses that rely only on human‑interaction friction (like visual CAPTCHAs) become latency hurdles rather than blockers when faced with persistent, automated agents. — If true generally, platforms and regulators must rethink interaction‑based defenses and add design and policy measures to stop autonomous agents from gaming timing, token, and account‑chaining weaknesses.
