The system automatically assigns or recommends people who are concerned, and it is confirmed unexpectedly. In this case, users may close some accounts without knowing it. However, Weibo often offers the option of canceling attention, and users can cancel these unwanted attention at any time.

Weibo's account has been stolen: This is a very serious situation. Hackers may use users' accounts for malicious operations, including automatically paying attention to some marketing accounts or other irrelevant accounts. If users suspect that their accounts have been stolen, they should immediately change their passwords and contact Weibo Service for handling.

Authorization of some applications or third-party applications: Some third-party application interfaces may automatically make users pay attention to many people, which is usually a means for network companies to use Sina Weibo users to brush powder. When users use third-party applications, they should pay attention to checking their permission settings to avoid unnecessary authorization.

The account is unsafe or synchronized with other related products: in this case, the user's account may be "hijacked" and praised and concerned under the control of criminals. Users should regularly check the security settings of their accounts and cancel the unnecessary synchronization of related products in time.
