Detection approach
FlareSolverr TAB→SPACE verification pattern detected. The CAPTCHA/Turnstile checkbox was activated via keyboard sequence instead of a real mouse click or touch event. Humans click; bots send TAB followed by SPACE through ActionChains.
How this helps detect bots
Collect this signal alongside session context, request metadata, and other independent indicators. A single anomaly is a lead, not a verdict; corroborating anomalies make automated traffic more likely.
Legitimate traffic to consider
Visually impaired or keyboard-only users using standard accessibility navigation.
