Google hasn't done a very good of implementing this particular memory hole. While they whacked thepeoplescube.com from the index, a search for "thepeoplescube" (no .com) still turns up 16,500 results, and it is unlikely that someone slipped and accidentally typed 'thepeoplescube' on their gardening blog when they meant to type 'cucumber.'
It'll be interesting to see if those 16,500 results that mention the site start dropping from the index as well.
Hmm. Do any of those 16,500 results actually point to 'thepeoplescube.com'? In any case, I never use google, so I'll not be seeing what happens with this. "Out of site, out of mind", heh heh...
