I believe SEO hosting is indeed a scam.
Google doesn’t need to see IP addresses to determine affiliations, they have the world’s largest link graph for that. In fact, that is the purported reason behind Brin’s desire to graph web page backlinks, which ultimately led to the development of the search engine known as Google.
To think that you can hide your affiliations by using different IP addresses is laughable to anyone who understands how large scale search engines work.
