Captcha in a Web-to-Lead Form
I am trying to add a captcha to my web to lead form in my website to get rid of spam. I haven't found a way that I can get saleforce to recoginze the lead, and for the captcha to work. Any ideas?
Web to lead to is just a form post, you would have to build something on your site to validate the CAPTCHA and submit the form.

For CAPTCHA on Force.com site see this link :https://developer.salesforce.com/page/Adding_CAPTCHA_to_Force.com_Sites
For your web to lead you would have to build similar capabilites client side to validate and submit.
Thanks,
