Implements Reverse CAPTCHA.

ATTACK_DETECTION_REVERSE_CAPTCHA enables the Reverse CAPTCHA attack detection feature for your forms.

Normal CAPTCHA uses image verification to force your users to prove they are human.

Reverse CAPTCHA is a more user-friendly method because it tries to trick a spambot into revealing it is a bot without requiring humans to prove they are human.

To implement Reverse CAPTCHA, you must perform the following tasks:

You should create random names for the two fields and a random value for the first field. By randomizing your Reverse CAPTCHA, you'll make it different from everyone else's and make it much more difficult for spambots to be created with a single method of attack.

ATTACK_DETECTION_REVERSE_CAPTCHA allows you to use any number of fields to implement Reverse CAPTCHA. However, at least one field must provide a fixed value and at least one field must provide an empty value.

If you don't want FormMail to perform this particular attack detection, set it to an empty array like this:

$ATTACK_DETECTION_REVERSE_CAPTCHA = array();

$ATTACK_DETECTION_REVERSE_CAPTCHA = array("cfld1"=>"q7ga","cfld2"=>"");

Where "cfld1" and "cfld2" are your random names for your Reverse CAPTCHA detection fields and "q7ga" is the random content of one of those fields.
