Commentary:

  • Inclusion in the list may result from past violations of the law or service’s rules or other evidence that a given user account or file may be malicious or inherently violate the service’s policies or applicable law.
  • Also known as a block list.
  • Sometimes called a “black list” although this term is now discouraged.
