Solving CaptchaFox Challenges
CaptchaFox is a privacy-first captcha alternative using behavioral and proof-of-work signals. The widget renders from a sitekey starting with sk_ and produces a cf-captcha-response token on completion. MeshPrivacy generates valid tokens by executing the challenge server-side.
