I have notied this guy flipping thru a few services with hundreds of sub-domains then suddenly dominating all search terms.
Check out this search for "milf pics"
http://www.google.com/search?q=milf+...start=100&sa=N
Notice all the listings
You would think google would limit a domain from holding so many spots in a row like that ( pages of them )
Ok now look at the google cache of any of those pages..
