    Question A Free Adless Captcha For My Website

    Following the increasing number of spam messages I am receiving from a contact form in my website, I want to implement a readable captcha that will authenticate message senders. If anyone knows of a website that offers free adless captcha that I can add to my website, please let me know. Thank you.

    white hat web design have a nice easy to use captcha but some bots are smart enough to OCR it and submit it with a valid code.

    Mix that into the mix with random field names (mrarrowhead.com) and a emailed confirmation link and you'll probably eliminate the spam.

    I've stopped nearly all spam from my contact forms by validating out the '<a href = ' in the body of the message. Most spam includes a web link.

    You could make the links nofollow...that way, those spam links will have no gain in Google page rank.

    PHP Code:
    <a rel "nofollow" href="http://www.codingforums.com/php/...></a> 
    Try Google captcha - easy to install and use.

    You could also try a blog comment hosting service like Disqus - they have data from multiple websites, so if an ip is flagged for spam on one website, it won't be allowed to comment on your website - does the job for you already.
