I use Imacros to automatically register on certain sites. For this task I use the beatcaptchas.com service. I've encountered problems on sites that use the mollom captcha. Basically, when the registration page is loaded captcha A is generated. With I macros I need to save the image to my pc and send it to the captcha breaking service. Using Imacros to save the image, another request is sent to the mollom api to save the captcha. With this action captcha B is generated and saved to my pc. Its frustrating. It will be really lame if this happens with the other captchas out there. Anyone can help? If you are not familiar with this captcha I can post an example site.
