Streisand effect

The Streisand effect is the phenomenon whereby an attempt to hide, remove, or censor a piece of information has the unintended consequence of publicizing the information more widely, usually facilitated by the Internet. It is an example of psychological reactance, wherein once people are aware something is being kept from them, their motivation to access and spread the information is increased.

It is named after American entertainer Barbra Streisand, whose 2003 attempt to suppress photographs of her residence in Malibu, California, inadvertently drew further public attention to it. Similar attempts have been made, for example, in cease-and-desist letters to suppress numbers, files, and websites. Instead of being suppressed, the information receives extensive publicity and media extensions such as videos and spoof songs, often being widely mirrored across the Internet or distributed on file-sharing networks.

Mike Masnick of Techdirt coined the term in 2005 in relation to a holiday resort issuing a takedown notice to urinal.net (a site dedicated to photographs of urinals) over use of the resort's name.

How long is it going to take before lawyers realize that the simple act of trying to repress something they don't like online is likely to make it so that something that most people would never, ever see (like a photo of a urinal in some random beach resort) is now seen by many more people? Let's call it the Streisand Effect.

The term invoked Barbra Streisand who had unsuccessfully sued photographer Kenneth Adelman and Pictopia.com for violation of privacy. The US$50 million lawsuit endeavored to remove an aerial photograph of Streisand's mansion from the publicly available collection of 12,000 California coastline photographs. Adelman photographed the beachfront property to document coastal erosion as part of the California Coastal Records Project, which was intended to influence government policymakers. Before Streisand filed her lawsuit, "Image 3850" had been downloaded from Adelman's website only six times; two of those downloads were by Streisand's attorneys. As a result of the case, public knowledge of the picture increased substantially; more than 420,000 people visited the site over the following month.
