Is it illegal to write an ebook like amazon ghost, amazon stealth or amazon suspension guide?

I know that Amazon suspends a lot of their sellers often & mostly without morals. I came across 3 eBooks that may be purchased where you can learn how to open another Amazon Seller account. My question is: is it legal for the writers to sell these types of books? Even if the books contain nothing illegal in themselves, will their selling of their books ever come back to bite them?
Can Amazon sue them for writing these books?
Examples:
AmazonGhost
AmazonStealth
The Ultimate Amazon Suspension Guide
