Drupal Forum Spam Cure

Ever since I set up the forums on this site a few weeks ago, I have been inundated with spam posts on them. I didn't want to require users to register, or answer a question prior to posting, so I installed the spam module. It's not a bad module for a simple implementation, and actually did block the majority of spam-bot posts, but it's not very granular (and understandably so... it walks a fine line of being easy to use and still effective, and does a pretty good job), and it was sort of hit and miss and there were many posts still getting though (even after tuning the custom filters for a few weeks), so I finally found the cure:

The Drupal Akismet Module

I used Akismet with Blojsom before and it worked great and so I was very excited to see a Drupal module for it. (Akismet requires an api-key from wordpress, which is free and can be acquired here)

After one week with Akismet, my 20-30 spam-bot forum posts that were getting past the Spam module a day have turned into ZERO spam-bot posts getting past Akismet.
