The message was sent, but it was rejected by the other party. What do you mean?

That means you've been hacked. Because the other party didn't want to accept the news of "you", they blacklisted "you".

1, blacking out, generally speaking, is to blacklist someone and block 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 a thing and a person who is separated forever in real life.

2. blacking out only blocks the communication between the other party and you, and he blocks any action of you. At this time, you are still his good friend, but because you belong to an "abnormal relationship", your existence can only be among his strangers! When he is not surfing the Internet at home, you will disappear from his strangers the next time he logs in. This also requires the response time of Tencent system, which sometimes lags behind! If you want to put it in a group outside the blacklist of strangers, it is equivalent to the same verification process of adding the friend again.

Extended data

Lahei deleted ~ it means he disappeared in your sight! In the future, you will disappear into each other's friends. Deleting friends takes time for the system to respond. If you surf the Internet at home, all this information will be automatically saved, so some records will not be changed immediately after you finish modifying them, and will only disappear after refreshing the system or reinstalling QQ! It is mainly the result of the lag of network response time!
