Proposing World-wide IP Banning of Spammers

...you are helping these spammers by posting clickable links to their sites?! This will help their search engine rankings. (OOPS!) :-)

You can unlink them if you edit the "http" and/or "www" out of the URLs in your post.

Look at Jeremy's Spam 2.0 module.

Features

* Written in PHP specifically for Drupal.
* Highly configurable.
* Automatically detects and unpublishes spam comments and other spam content.
* Automatically learns to detect spam in any language using Bayesian logic.
* Automatically learns and blocks spammer URLs.
* Automatically blacklists IPs of learned spammers, preventing them from posting additional spam and wasting database resources.
* Detects repeated postings of the same identical content.
* Detects content containing too many links, or the same link over and over.
* Supports the creation of custom filters using powerful regular expressions.
* Can notify the user that his or her content was determined to be spam, preventing confusion over why their content doesn't show up.
* Can notify the site administrator in an email when spam is detected.
* Provides simple administrative interfaces for reviewing spam content.
* Provides comprehensive logging to offer an understanding as to how and why content is determined to be or not to be spam.

Add-ons

* Spam SURBL, supports six Spam URI Realtime Blocklists
* Trackback Blackhole, to block trackback spammers on sites that don't use the trackback module.

Also, look at the Bad Behavior module -- it will prevent the spam bots from easily accessing your comments system (which will reduce server load if you get hit a lot).

I use Spam 2.0 on every site that is open for comments.
