Apple 7 hacked a person's number, can you receive the short message from him?

I can't. If the phone settings blacked out the contact, then the contact can't call and send text messages to your phone, and the system will automatically intercept it, just like intercepting harassing calls.

The word blacklist comes from world-renowned universities such as Oxford and Cambridge in Britain. In the early Middle Ages, these schools stipulated that the names and behaviors of students who committed bad behaviors should be recorded in black books. Whoever is named in the black book, even if it is not notorious for life, will make people lose their reputation for a long time. Students are very afraid of this regulation of the school, and they often take care to prevent deviant behavior.

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, and 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.
