In novels, this kind of situation was often called " malicious comments." These comments could be for various purposes, including leeching off popularity, malicious attacks, pranks, and so on. If there were too many comments, it might cause trouble for the singer and affect her reputation. Therefore, the singer might consider limiting the number of comments. The other possibility was that the singer might not want malicious comments to affect her reputation. If comments are restricted, then these comments may become more hidden and may be harder to discover. The singer might want to protect her reputation through her own efforts rather than relying on limiting the number of comments. Of course, the specific situation might vary according to the plot of the novel. However, under such circumstances, the singer might consider limiting the number of comments to protect her reputation and avoid unnecessary trouble.
