I noticed some websites have now done reversed manipulation before penguin 2.0
Looks like they knew what was coming.
They added links pointing to their important pages with keywords like company name or some other unimportant term so their keyword does not take a hit. I saw one of my competitors doing some strange things before the update. He made all his top pages no follows and added these links. The pages where dropped from the index for about a week.
Then he took the no follows off. Now his site is on top for all his key words makes you wonder?
