Blacklisting

Blacklisting is the act of creating a list of people, organizations, products, or services that are considered undesirable or untrustworthy and are therefore to be avoided or denied certain privileges or opportunities. This practice is often implemented to exclude, punish, or ostracize individuals or entities based on perceived transgressions, affiliations, or beliefs. The consequences of being blacklisted can range from social isolation and reputational damage to economic hardship and legal repercussions. The criteria for inclusion on a blacklist are often subjective and may lack transparency, leading to potential abuses and limitations on freedom of expression and association. This practice is used across many sectors and is seen differently depending on the reasons the person or entity is blacklisted.
