Dogpiling (Internet)
Dogpiling, dog-piling or simply a piling-on is a form of online harassment 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. 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. Participants use criticism and/or insults to target a single person. In some definitions, it also includes sending private messages.
