I have been thinking the same thing, I am getting away from anything Google.
It could be anything they use to tie one site to another, links, adsense, analytics, ip'.. I am making some new sites to test this out with no footprints for them to follow.
I know people that were untouched Panda in any way and they don't make it easy for Google to follow on purpose.
