Only FriendlyCaptcha v1 is supported. v2 is not supported yet.

FriendlyCaptcha v1 is a proof-of-work captcha that runs a puzzle in the background. No user interaction required.

Finding the site key

Look in the page HTML for the v1 widget:

<div class="frc-captcha" data-sitekey="FCMST..."></div>

The site key starts with FCMST followed by alphanumeric characters. If you see a different format (e.g. starting with FC2), that's v2 which is not yet supported.
