Requires Captcha

Does work with the latest Captcha API update. New release 28.03.08

Inspired by this discussion and the fact that many Drupal pages are plagued with endless amounts of spam. While modules like akismet and spam offer a great way of filtering the spam after it's being submitted the purpose of Riddler is to compliment these modules by catching it before it gets submitted.

What exactly does it do?

This module will add a 'riddle' to a form of your choice (using Captcha) requiring guests to answer the 'riddle' before being allowed to submit the form.

This is the default question:

• Q: Do you hate spam? (yes or no)
• A: yes

Questions and answers can be customized through the '/admin/user/captcha/riddler' page.

How to display question in different languages with i18n

Add this to your settings.php (if you already have i18n_variables, add these instead of overwriting)
$conf['i18n_variables'] = array(
'riddler_question',
'riddler_answer',
);


Then visit /en/settings/riddler and /is/settings/riddler (is being your country code) and set the settings differently. This will allow Form Riddler to display different questions for different language settings.

Planned features:

• Multiple random questions

Note that the test-comments here are periodically deleted and I have yet to get a single real spam here
