We are on this site as well. It is quite odd and appears like a search site that is taking content from our page to attempt to make a description, kind of like Google, MSN or Yahoo does. But it seems they mostly scrapped our footer links which I can’t understand why that would be of any value for this site.
I will take Dom’s advice and catch up on that blackhat forum sometime, but are we sure this isn’t just someone’s attempt at creating a search engine for all of us affiliate sites? They claim to have over 327,000,000 pages indexed.
