if a site show a white bar (not grey bar) in the google toolbar, would it b safe to say that the site is not banned by google? site:www.domain.com and link:www.domain.com shows 0.
Of course they are not banned, if they were banned they wouldn't be on G index. Probably it his a new domain (showing PR=0 and BL=0)
He is saying they aren't indexed by google. Did you previously get results by just typing your url into the search box? (By the way being banned has nothing to do with grey/white)
