Hi All again,

I've been working on a directory script. A month or so ago I inquired about the captcha script.

Since then I started validating email addresses with PHP and validating IPs against a log of banned ip's (nested in a php file).

So the question is do I really need to add the captcha code as a third layer of spam protection?

This is not a working directory yet. I have to switch domain names. Just using this url as a test. It will still work long after I got the new domain, just nice to be able have a test url.

Later

Depends on if you think spammers can get by your first 2 layers. In all cases, the more protection you got, the better you are :P

As a side note, this needs to be moved to the off-topic forum :D

Hi again,

Well I got my captcha script working... because of the following article..

Here is an article I found while searching Google.

Why IP Banning is useless
http://kalsey.com/2004/02/why_ip_banning_is_useless/

So I still have two layers of security...
(1) email validation
(2) captcha
