Reports over at WebmasterWorld show major shifts taking place within the Yahoo! search results. Some are reporting many junk sites filtering the population. Some believe it has to do with the Link Command Being Updated, but others are not sure. One member reports that "several referrer spammers I have been tracking have lost all their spammy backlinks -- hasn't affected their rank though." It is always funny how things improve so much for some and so little for others. No official weather report from Tim Mayer at Yahoo! as of yet.
