If the author doesn't update, why is he called a eunuch?

The term " eunuch " was often used to describe authors of novels, web novels, and other literary works. When they stopped updating or publishing new chapters, readers and critics would call them " eunuchs." The meaning of this word was to stop the progress of the novel or story, which meant that the plot did not develop and lacked new excitement and surprises. Sometimes, the reason for a eunuch was because the author was sick, unemployed, or died, but more often, the reason for a eunuch was because the author had no motivation or willingness to continue writing or was unable to maintain the enthusiasm and motivation for writing. Therefore, the word " eunuch " was not a negative evaluation of the author, but a neutral description of the literary works that had stopped updating.
