I have long suspected that Google follow "nofollow" links but two bits of news in the last week confirmed it to me at least.
1. Payday Loans - if you track the top SERPS in Google UK several of the redirecting blogs are ranking almost entirely on comment spam with "nofollow" tags in links.
2. PRISM - putting aside the politics what is clear is the NSA rely on Google to tell them what's happening online. As a collector of data to the US Government you need to be crawling everything you can. So you follow all links.
