Dogpiling,dog-piling or simply a piling-on is a form of online harassment [1] or online abuse characterized by having groups of harassers target the same victim. Examples of online abuse include flaming, doxing (online release of personal information without consent), impersonation, and public shaming. [2] [3] Dog-pilers often focus on harassing, exposing, or punishing a target for an opinion that the group does not agree with, or just simply for the sake of being a bully and targeting a victim. [3] Participants use criticism and/or insults [3] [4] [5] to target a single person. [6] In some definitions, it also includes sending private messages. [7]
The expression comes from the dog-pile in American football, in which a person who has the ball is targeted by the entire opposing team who come and jump on him. It became popular with the rise of social networks.
Dogpiling is a form of bashing to which a pack effect is added, creating a collective scapegoat.
The victim of dogpiling feels isolated and can hardly defend himself. It can have difficult psychological consequences.
