Talk about a maze. I was checking one of my keywords at Yahoo and found down at the number 10 spot a listing for what would appear to be a Google Group covering the subject. The url should have told me something was most probably amiss.
The arbitragers are getting really creative. But I really want to know how they got someone at Google to create the redirect. It is a little hard to do that without access to the server.
Now you aren’t finding the result in the Google organic results, so I guess Yahoo places more stock in Google Groups than Google itself! After this they may be a little less likely to do so.
