Avoid guestbook spam

I use this guestbook: <[login to view URL]> Although it has the possibility to block IP nummers to avoid spam, some of them are capable posting commercial notes using different IPs (using scripts or any other way to get those messages posted on a regular basis). I intendED to avoid the spamming of the guestbook implementing graphics (try posting a message at [[login to view URL]][1] to see hat I mean). Now an entry is only added reading the string and entering it manually. For some reason they still are capable of posting messages. Even when posting messages does require a password (configuration option in the administrators interface) , I'm looking for someone capable of implementing both. Looking forward to your reaction.
