Homonym: blacklist (Censorship)
A "blacklist" is a list of individuals, organizations, or entities that are denied certain privileges or services. This can occur in various contexts, such as employment, finance, or online platforms. Being on a blacklist often means that the person or entity is considered untrustworthy or problematic.
Blacklists are commonly used in industries like cybersecurity to prevent access to sensitive information or systems. They can also appear in credit reporting to restrict loans or credit for those with poor financial histories. The opposite of a blacklist is a "whitelist," which allows access or privileges.
