I give up. The spambots seem to have figured out a way around every built in anti-spam feature of the PHPBB Message Board systems. So I added a line of code to make sure the user is logged in to SuddenDeath.org first and if not it bounces the user back to the home page.
This does mean that for the time being you have to register twice- once with the web site and again with the message boards. When I get a chance I'll try to figure out a way to pass through the main login to the message boards, but honestly this isn't a high priority at the moment.
Sorry for any inconvenience. I really wanted to keep them public, but I can't be manually deleting 25 posts a day about the latest virus infested porn site. I have music to work on.
