Well, I've known several people over the years who have created a multitude of accounts for the purpose of selling them when they reach around 100K karma to various activist and political groups. He didn't care what they were doing with the accounts, but it seems there's been a black market for user data and user profiles with high Karma counts for a long time now.
The only things I can think of Google using that data for are for nefarious purposes.
