Google, for whatever reason, thinks that a very light touch with regard to spam sites is appropriate. (Although Cutts is right that an inurl: or site: query doesn't show anything - he's saying, "Show me a real-world query that has nothing but spammy results and then I'll do something").

I think and have thought that a Google competitor could come along and beat them by having a heavy hand against spam sites. If it's designed to attract search engines, NewGoog doesn't index it, period. Any business generating datafog for search engine consumption gets deindexed entirely and permanently.

Go ahead, type any question you want into Google. ANY question at all. You get a list of 500 search engine question spam sites, most of which are written in broken English and contain more or less nonsense strings of words thrown together. NewGoog would wipe all that shit out.

Attention Google: offer an option (like SafeSearch) that applies a HEAVY HAND to spam sites. We will love you for it.
