The GeoBlocker module allows site maintainers to black-list or to white-list access to a Drupal site by countries. IP tables come from http://www.php.net/source.php?url=/include/ip-to-country.inc and are downloaded locally to speed up lookup.

Hidden CAPTCHA is an extension to the CAPTCHA module. It offers a hidden CAPTCHA (duh!)
The idea is very simple: If you offer an input box in any form, 99% of the time, robots will fill it with something before posting the form. If you offer an input box that has to stay empty, then the CAPTCHA system will prevent posts by robots.
This module allows you to add a Hidden CAPTCHA on forms where you don't absolutely need to have a human enter a text, number, etc. but that still needs a little anti-spam control.
How does it work?
This is just like any text CAPTCHA. You can set it up with a question specific to your website or that people just cannot answer in their right mind (i.e. How many stars are they in the Universe?) By changing the question regularly (once a month?) then you can prevent even more spam as the spammers need to adjust their robots to understand the new question (and some won't do that...) Long questions are better since they are not very likely to have been asked in any CAPTCHA before.
The CAPTCHA system will create a form with your question and an input box. The Hidden CAPTCHA system adds a specific CSS class to that form. The class references a CSS definition in the Hidden CAPTCHA file that says that the whole CAPTCHA box shall be hidden (i.e. display: none;).
