The word " circle " in web novels might be blocked mainly because it might be mistaken as a violation on some platforms. The word "circle" can refer to a particular community, hobby, or culture in some cases, but it can cause misunderstanding or offend others if used incorrectly. Therefore, in order to avoid unnecessary trouble, some platforms would block some ambiguous or sensitive words. However, some platforms would also provide relevant explanations and explanations so that users could use words more clearly to avoid misunderstandings. Therefore, the specific reasons for blocking may vary from platform to platform. When using online novels, users should pay attention to the specifications and instructions of the platform.
