2011 British privacy injunctions controversy
The British privacy injunctions controversy began in early 2011, when London-based tabloid newspapers published stories about anonymous celebrities that were intended to flout what are commonly (but not formally) known in English law as super-injunctions, where the claimant could not be named, and carefully omitting details that could not legally be published. In April and May 2011, users of non-UK hosted websites, including the social media website Twitter, began posting material connecting various British celebrities with injunctions relating to a variety of potentially scandalous activities.
