How does scrapebox actually work? I know it does blog commenting on domains with the comments box. What if; the domains doesn't have any comments box? e.g: http://www.anderson.edu/ (I found through bhw from .edu bloglist) Also, what if the bloglist requires a sign-up and captcha? So far, I haven't been asked to solve a captcha when using it or goes through registration and email verification and all those stuff.
