Just wanted to see if there are any plans on integrating something like Death by Captcha (www.deathbycaptcha.com) to improve crawling of search engines. It's a pretty easy to use API, would be easy to integrate.
We have managed to create a similar service to this requested feature at http://www.submitia.com/de-captcha.php which is on a pay as you go basis image recognition web service at $0.0025 per captcha image solved.
Take a look at it at http://www.submitia.com/de-captcha.php
We currently use Anti-Captcha for another SERPs service we have and it appears to work well but I do prefer the depth of analysis that SEO Panel provides.
