Im using this plugin
Peter’s Useful Crap » Version 2.6: Peter’s Custom Anti-Spam Image Plugin for Wordpress on the site in my sig, it seems to be working pretty good. I was deleting shit loads of spam posts per day before using it. I still get some spam, but its user generated spam and not the auto spam that can become overwhelming.
OFF TOPIC;
We were supposed to swap links, if still interested shoot me a PM
