Record the ip of the spammers and block them.

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

So you haven't tried blocking ips?

Maybe there is something wrong with the logic of your script? Why don't you post the code in the asp forum: http://www.daniweb.com/techtalkforums/forum18.html I'm sure someone there will have an idea for you.

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
