IT: Google Spam Filtering Gone Bad

[Seth Finkelstein]

In the past few days, there's been a problem with Google. For certain
combinations of search terms, Googe has returned no results or very
few results.

This has been documented on the "GoogleWhack" site ( http://googlewhack.com/ )
on the page "Google NACK" - http://googlewhack.com/nack.htm

I believe I have discovered the cause. I conjecture it is a consequence of
Google trying to eliminate spam search results, but instead, in certain
cases, wrongly eliminating all subsequent search results. See:

Abstract: This report describes a problem which caused Google to
return very few, or no, results for particular combinations of search
terms. It is almost certain this is a consequence of search results
being post-processed by spam-defense which has gone awry.
