http:BL

Implementation of http:BL for Drupal. http:BL can prevent email address harvesters and comment spammers from visiting your site by using a centralized DNS blacklist. It requires a free Project Honey Pot membership. This module provides efficient blacklist lookups and blocks malicious visitors effectively.

http:BL has been adopted for use to enhance protection on Drupal.org.

Features:

• http:BL lookups for visitor IPs
• Blocking of requests coming from blacklisted IPs
• Database caching, decreasing the number of DNS lookups
• Honeypot link placement on ban page and optionally in footer
• Custom ban message
• Whitelisting through the access table (admin/user/access)
• Greylisting: grants the user access if they pass a simple challenge
• Greylisting threat-level threshold configurable in admin settings
• Blacklisting threat-level threshold configurable in admin settings
• Length of time cached visits are held are determined by configurable admin settings
• An option for checking only when a comment is placed,
  queueing the comment for moderation if the lookup is positive
• Basic statistics on the number of blocked visits

Note that the module can also function without http:BL functionality -- its use will then be limited to the placement of a Honeypot link in the footer.

Drupal 7 version now available

Additional Features:

• Optional 3 levels of logging (Error only, Positive Lookups or Verbose - for testing and gaining trust)
• Default Views included (identify blocked and whitelisted IPs with links to their Honeypot profiles)
