Some time ago, Bill Dembski’s weblog, Uncommon Descent, was de-indexed from Google. My assertion at the time was that they had purposely taken that step to avoid the Google cache of material. I was wrong about that. I received email today from UD admins that was cc’d in correspondence with Google’s webspam head, Matt Cutts. That email made clear that UD had suffered a cracking exploit, much as the TalkOrigins Archive recently did.
The UD people were victimized, and not seeking to eliminate their site from the Google cache.
