Iron Curtain

Developed by Reload, sponsored by Scribo.

This module allows the site admins to restrict access to certain paths or the entire site, based on the visitor's IP address.

It allows users with a certain role to bypass the system, it allows a list of paths to bypass the system and it allows you to make a list of paths which can only be seen by whitelisted IPs, and another list which can not be accessed by blacklisted IPs.


Maths Captcha

This adds a simple maths-based question (e.g. what is 5 plus 8?) to selected forms to help test whether the user is human or not.

Users with appropriate permission can specify a list of form ids to protect, which can include wildcards like foo*

The question is inserted before the first submit element, or at the end if a submit element cannot be found at the time hook_form_alter() is called.

It is a stateless mechanism, so no session variables/cookies are required. There is a 15 minute timeout from generation to validation.

Ban By Referer

Ban by Referer allows you to create blacklist for referrers.

Spaces Enforced!

We all agree that spammers don't use spaces in their usernames, right? This module forces users to use spaces in their usernames so that spammers can't register (until they figure out a way to). With the 7-x.1.1 version, you can now specify your own character and how many times this character should occur in the username.

#D8CX: I pledge that Spaces Enforced! will have a full Drupal 8 release on the day that Drupal 8 is released.
