I am desperate. Guestbook on my website is full of spam. And every day I receive more and more spam so this guestbook has become unusable. I would really appreciate if you could explain to me how to remove spam threat to my guestbook. Thank you in advance for your suggestions.
Spammers are using robots or bots to search and place spam at available places. You should first change the address of your web site because it is compromised. Just put a tag on page with text pointing to a new address until visitors update their links. Second, and most important, disable possibility of HTML messages in your guest book. You can still use URL tags but in text mode these links will not be alive.
