There are people who want to publish their content, but they do not consider themselves good enough at writing, so they hire a ghostwriter or ghostwriting agency, who will take care of everything related to the text and its details, but it does not appear in the work, it is anonymous. A ghostwriter is someone who is hired by an author or company to make a text from which they do not receive any public recognition. They are generally hired to write novels and autobiographies, short stories or articles, and remain anonymous or as a contributor. Did you ever hire such a writer before?

I was thinking
horror story writer but this is another thing

The common definition of ghostwriting is the act of 1 individual writing in the call of every other individual, group, company, or organization without receiving a public credit. But greater regularly than not, ghostwriting is a custom designed shape of collaboration, protecting a variety of relationships and offerings tied to the authors’ needs, objectives, and work style.
