Just a heads up with some very useful information to any new customers (or members) launching new or existing web sites. Of course this information is not for the savvy type, as we all understand this, but some may not.

With the launch of our new 2006 ILance web site, we implemented a new security feature on all contact forms that require human input. It's basically a security "image" that is displayed and then requires the user to enter the characters within the image to continue.

There were a few times on the old site that had our inbox bombarded with emails from robots actively crawling through the web looking for spammable mail forms, and it happened quite a few times. Knowing the new site was coming :rolleyes: , we simply added the IP address of those robots to our deny list. The problem continued at least once or twice per month.

Anyways, 2-3 months later with the new site up and running, there has been 0 spam attempts and our inbox is clean :D

If you are interested in the PHP code to make this happen, let me know and I'll post it as a reply.

Regards,
Peter

CAPTCHA is a great tool. We are actually working on a new version of a captcha module that allows both text and voice recognition to allow users that might have a hard time visually reading the lettering to listen to the alphanumerical coding to input into the associated box.
