Record the ip of the spammers and block them.

[msaqib]

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.

Is ther any other way to block such spams ??
thanks
