Google can go fuck themselves as far as I'm concerned.
In terms of business models, I actually think that you are better off creating hit and run sites frequently, spamming them and ranking them temporarily then moving on to another one when it gets slapped. Let's face it, blackhat links are easier to get than whitehat links. Why put all that time and effort into a single white hat site when Google can come along and fuck you over for no given reason? Diversify with your sites but there is no doubt that even now, in 2013, you can still rank a site with spam and spam alone, end of story.
