Internet vigilantism
Internet vigilantism is the phenomenon of vigilantic acts taken through the Internet (the communication network or its service providers) or carried out using applications (World Wide Web, e-mail) that depend on the Internet. The term encompasses vigilantism against scams, crimes, and non-Internet related behavior. It was termed “digilantism” in the wake of the Boston Marathon Bombing.
Some have suggested that the internet’s lack of central control has prompted a tendency towards vigilante reactions against certain behaviors in the same way that they have prompted those behaviors to occur in the first place.
