Blacklisting is the action of a group or authority, compiling a blacklist of people, countries or other entities to be avoided or distrusted as being deemed unacceptable to those making the list. If someone is on a blacklist, they are seen by a government or other organization as being one of a number of people who cannot be trusted or who have done something wrong. As a verb, blacklist can mean to put an individual or entity on such a list.
