I hate to say this, but you guys might as well disable registering for this forum until this issue is fixed. I've got like two spambot mails, and several spambot posts over the forum have been appearing over the months. I'm certain you mods/admins are aware of this issue and are probably sick of deleting those kind of posts already, but it seems like nothing is actually being done to prevent it. I think this has been happening over several forums with a similar anti-spambot system (forgot what it was called) that seems to have become exploited though. I bet there have been more spambots registering here than real people over this time...
