When WeChat blackmails the other party, the other party will not receive any prompt. You are still on the other person's friend list, but the other person will know that he has been blacked out in the following two situations:
1. The other party tried to send you a message, but it refused.
2. The other party can't see what you send in the circle of friends, and can't enter your circle of friends.
Blackmail usually means blacklisting someone and blocking his speech. Black screen usually refers to blacklisting someone and blocking their speech, which is suitable for chat software such as Tencent QQ and some online games. As a fashion expression, it can be extended to the emotional rejection of one thing and a person who will be separated forever in real life.
