Yeah that is the easiest work, but they are using the spam IPs means those IPs are not real and are from different countries. Thats why i can not block them.

If you have any other idea?
please let me know, coz i got 100 guestbook entries in the last 24 hours.

. Thanks

wel i have already blocked hundreds of IPs, but every time the spammer uses the new IP.
Is ther any other way to block such spams ??
thanks
