Yes, you keep parroting the same thing but that doesn't change what other people are saying - that it's more than what you say it is.
You misunderstood Suzanneh, SEO101, Travler, Lysis and anyone else that mentioned that.
What they suggested was adding rel="nofollow" to suspect paid links (or self-owned links) so they won't cause you issues with Google. That in itself will not provide rank recovery. All you did was align to TOS.
At best... nothing will change.
At worse... if such links you added rel="nofollow" to were not previously impacted by PENGUIN you just did that yourself and your results will drop even farther. But you don't have any webspam anymore... so start getting more links.
I'm sorry to say the cause & effect of DIY SEO when you don't have a clue what you are doing is a huge part of the problem.
