Gary Price of Search Engine Watch Blog has found yet another Stanford research paper . In this paper we study how web pages can be interconnected in a spam
farm in order to optimize rankings. We also study alliances, that is,
interconnections of spam farms. Our results identify the optimal
structures and quantify the potential gains. In particular, we show
that alliances can be synergistic and improve the rankings of all
participants.Seems like old news to me :)
