The word blacklist comes from world-renowned universities such as Oxford and Cambridge in Britain. In the middle ages? These schools stipulate that students who misbehave should record their names and behaviors in black books. Whoever has a name on the black book, even if it is not notorious for life, will make people lose their reputation for a while. Students are very afraid of this regulation of the school, and they often take care to prevent deviant behavior.
This method was borrowed by a British businessman at that time to punish customers who often failed to pay back their credit, respected their contracts and kept their promises.
British businessmen listed the names of such customers on the black book, and later listed some names that were bankrupt and about to go bankrupt on the black book. After the news spread, it caused a sensation in society. First, businessmen rushed to follow suit. Then, black books appeared in all walks of life. Many factory owners listed the names of people who joined the union under the column of "no employment" As a result, the blacklist was secretly passed around between factory owners and shop owners.
1950 In September, the US Congress passed the Macaron Act. In February of the same year, President Truman issued an order announcing that the United States entered a "state of emergency" and formally implemented the McCullough Act. They compiled various blacklists and arrested a large number of tyrants by name. As a result, the practice of blacklisting has been revised.
QQ blacklist
If you delete your friend, but you are still in his QQ, the message he sends you will appear among your strangers. You can blacklist him directly, and you will be deleted by his QQ number ~
Blacklist can keep you from being disturbed by someone forever. After adding a friend or stranger to the blacklist, he can't send you a message or send a message asking you to add him as a friend unless you delete him from the blacklist.
If you drag a person into my QQ blacklist, it seems to him that you won't disappear from his friends, but the other person can't contact you and send you a message, but you can't receive it. Also, your QQ in his friends is no longer updated, and the custom icon has become the original QQ icon, which is similar to QQ.
Drag into the blacklist, delete all records, and each other will disappear into each other's lives. I will never see his head light up again, I will never hear from him again, and I will never have more words to remind you whether you are happy or sad. Everything is left to time.
As the hour hand turns round and round, the pages of the calendar are torn off, and it will gradually fade out of your memory. ..............
