WWW_CAPTCHA_BADGE

This configuration variable defines a secret badge or key that can be used in conjunction with any of the supported Captcha solutions as an added layer of security against bots. If defined, the login, new password and subscription screens will not accept any requests without this badge or key. This prevents bots from bypassing the Captcha challenge by making calls directly to WA without going through the web interface. If enabled, copy and paste your secret badge into the captcha.keys configuration file in the "captcha" folder in your archives directory. This secret badge can also be used without a Captcha solution but will be less effective because it's submitted as a hidden form field and will be visible to bots in the source code. The secret badge can be any alphanumeric combination of letters and numbers. It cannot contain spaces or other special characters.

This configuration variable is not set by default..
