The source of the blacklist

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.

In today's network SEO optimization, the list of search engine spammers collected by search engines or voluntary users can be used to prevent these spammers from entering search engines or boycott them.
