In the past I attempted to report spam abuse, but it never helped. I get so little now that I simply delete whatever makes it through. Spam is a cronic problem and it can certainly waste a lot of your resources.

First you need to have some verification in the guestbook to prevent automated spams through software. This reduces half of the risk. Then for the manual spammers, nothing else than deleting and banning the IP from your server works to stop the spammers from coming in and trying to spam again.
reCaptcha verification is one of the options that can prevent spam. Also, you can discuss the same with your host, as various hosting companies have their own way to explain and discuss on reporting, blocking spam in the websites they provide hosting for.
