AdNauseam is a free browser extension designed to obfuscate browsing data and protect users from tracking by advertising networks. At the same time, AdNauseam serves as a means of amplifying users' discontent with advertising networks that disregard privacy and facilitate bulk surveillance agendas.

TrackMeNot blends software tool and artware intervention in a browser extension to protect users from data profiling and intervene in the power dynamic between searchers and the corporations controlling our data. Unlike most privacy tools, TMN works not by means of concealment or encryption, but via noise and obfuscation, periodically issuing algorithmically-generated decoy queries to search engines so that users' real searches, lost in a cloud of false data, are hidden in plain view.
