I found this article at Seobook.com and it was kinda unfair with ordinary webmasters like us.
Quote:
Business.com... - sells links (yes they have editors, but when they were interviewed about a year and a half ago by Aviva Directory they only had 6 editors managing 65,000+ categories...many of the listings not only included aggressive anchor text, but also allowed the use of up to 5 spammy sub-links with each listing)
- used nofollow on many of the free editorial links (while passing link juice out on the paid links)...this was corrected after we gave them a proper roasting on Threadwatch
 - uses a funky ajax set up to hide work.com content in a pop up (but makes it accessible to the Google crawler)
- scrapes Google search results as "web listings" and in some cases Google ranks these pages! (Google is ranking a Google search result surrounded with Google AdSense ads, branded as Business.com)
