Why is the message displayed when it is intercepted?

1. The sender of harassing messages will keep trying to send harassing messages, even if they have been intercepted, they will be displayed.

2. The sender of harassing short messages will change the sending number, making the previous interception settings invalid.

3. There is misjudgment or omission in the interception setting, which leads to the harassment message being intercepted by mistake.
