I think that Google have always pre-sorted the results to some degree otherwise you would have "how to build a nuclear bomb" online. There is a growing number of people that believe Google is the internet and of course it isn't. Maybe its 30% of it something like that. It doesn't display all the results it indexes, never has done, so it wouldn't surprise me at all if pre-sorting has been extended.
Is pre-sorting a prerequisite to categorisation of websites? I certainly could see how that could work with a background colour showing each category (green for information sites, blue for ecommerce etc) and the heavier the background the more emphasis on that category.
In order to do this you would certainly need to appoint authority first and that brings us back to Penguin 2.
It's like Google's trying to decide who to include rather than who to exclude
Perhaps Penguin 2 works in a reverse order deciding authority based on weight of positives as well as negatives. This would certainly account for websites that have been affected that didn't build links at all. And explain Google's reference to grey area website's.
What we do know is Google is looking at punishing Black Hat Seo here, but rather than simply penalize I think Google is balancing a positive against a negative.
So Factors That could count against you IMO:
1. Links from bad neighbourhoods
2. Unnatural link patterns such as forum signature, comment and directory.
3 Unnatural links from syndicated articles.
4. Unnatural diversity of links indicating paid link schemes.
5. Unnaturally high keyword density in internal links.
Factors that could count for you IMO:
1. High quality inbound links.
2. Engagement and user retention
3. Social Media Signals
4. Strong internal structure and few Errors
