I have a "new and unregistered users" portion of my forum that allows guests to post without signing up. I figured this would be good for non-technical users who couldn't figure out the registration process or for people who wanted to report a bug or some problem with logging in or registering, or just a place for people to voice their opinions without registering. Unfortunately this also brings with it spammers posting, most of the spam gets thrown into a moderation que but I'd like to utilize the spam cleaner on all of the spam. I figure it will block IPs for future use at the least right? Why would it not be available for Guests and not be able to search on the IP that posted the spam and remove all things from that IP?
