I have a doubt .. Consider abc.com(MONEY SITE) is a site with unique content and backlinks only with high PR and authority backlinks .. TIER 1 will have abc.blogspot.com(OFFICIAL) and a few more tier 1 sites .. TIER 1 is drip fed with random backlinks .. TIER 2 will have keyword.blogspot.com which is pointing only to OFFICIAL web 2.0 site with scrapebox blast .. QUESTION : With the money site rank for the keywords ?? Is it whitehat ??
