Whether it is illegal to write articles for others depends on the situation:

1. It is natural and legal to write the content of the article on behalf of others. If it is illegal, ghostwriting is illegal.

2. For the customer object of the service, if the content that the customer wants to write is illegal, it is to write for others knowing that the other party has violated the law.

Organized ghostwriting, if the circumstances are serious, constitutes the crime of illegal business operation. The understanding of "violation of state regulations" in the crime of illegal business operation, if an act does not violate state regulations, but only violates local laws and departmental rules lower than state regulations, certainly does not constitute the crime of illegal business operation. If an act violates the provisions of the state, but the provisions of the state do not make it a crime to be investigated for criminal responsibility, and the criminal judicial interpretation does not explain the act as a way of illegal business, of course, it does not constitute the crime of illegal business. It is illegal to write papers on behalf of others.
