I think google didn't have clear vision about what it will consider as natural.
The problem is you do not have a clear vision of what SEO is, what is natural or unnatural escapes your understanding. In most countries it is not only illegal to practice medicine or law without a license, it is immoral. Likewise, it is highly immoral of you to peddle worthless SEO services and it should be illegal. You are fortunate there are no laws prohibiting your shoddy services because you would be sitting in jail today. It is good for the world, business and for society that Google is weeding you out.
You ask for help, I gave it to you. Now I am giving it to you again. This is my gift, the gift of merciful counsel. If you wish to continue in the profession it would serve you well to take down your shingle and commit yourself to learning your trade and mastering it. Then and only then can you show your face in respectable society and offer your services.
