Streisand effect
The Streisand effect is a 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 that some information is being kept from them, their motivation to access and spread it 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 files, websites, and even numbers. Instead of being suppressed, the information receives extensive publicity and media extensions such as videos and spoof songs, often being widely mirrored on the Internet or distributed on file-sharing networks.
