A post over at JimWorld brought up a valid point. If Google doesn't want people to sell PageRank, why do they distribute their PageRank to a page that is doing so?
Google basically says, do not do what this page is doing. Passing its PR10 to the page, which is reported to have a PR9 now. The PR9 page is then selling that PageRank to the top bidders. Of course it is possible that Google is not allowing that page to distribute the PageRank but it is not stopping them from selling it. What would, in fact, stop them from selling the PageRank is by making the PageRank of the page a PR0.
In addition, if Google does not want people to use products like Webposition Gold, then why do they mention the company by name in their Quality Guidelines?
Is it like the Biblical story of Adam and Eve and eating the forbidden fruit?
