WiFiTagger is a new form of digital graffiti. The concept allows users to add their own comments to an unlimited number of nearby wifi networks. Under the name of the network, WiFiTagger lets you add up to 4 lines of 32 characters. Anyone with a wifi enabled device can tag this digital space. The hack was developed by F.A.T (Free Art and Technology) and artist/researcher Addie Wagenknecht.
The ability to tag digital spaces can be seen as a consequence of increased regulation on the streets. It is likely that more online spaces and hacks will be developed to widen the scope of digital civil disobedience.
