Buying or selling links that pass PageRank can dilute the quality of search results. If you believe a site is engaged in buying or selling links that pass PageRank, please tell us about it. Participating in link schemes violates the Googles Webmaster Guidelines and can negatively impact a site's ranking in search results.
