streisand effect - Computer Definition
An attempt to suppress information online that winds up making it more public. For example, if a hack that circumvents copy protection is published on the Web, as soon as it is legally challenged, numerous other sites copy and distribute the data. The term comes from an incident in 2003 when photos of Barbra Streisand's residence became even more public after she tried to prohibit them.
