Deplatforming, also known as no-platforming, is a form of political activism or prior restraint by an individual, group, or organization with the goal of shutting down controversial speakers or speech, or denying them access to a venue in which to express their opinion. Tactics used to achieve this goal among community groups include direct action, and Internet activism.
It is also a method used by social media and other technology companies to selectively suspend, ban, or otherwise restrict access to their platform by users who have allegedly violated the platform's terms of service, particularly terms regarding hate speech. [1]
