A British court has sentenced two men to four years in prison for their failed attempts to use the social networking site Facebook to incite rioting during last August's unrest in the country.
Appeals by two men jailed have been rejected by the Court of Appeal.
Jordan Blackshaw, 20, and Perry Sutcliffe-Keenan, 22, were convicted of creating Facebook pages aimed at encouraging violent disorder in their hometowns in northwest England.
At a 27 September hearing, the pair's lawyers argued that their four year sentences were "manifestly excessive".
Both men pleaded guilty to creating the pages, which were entitled "Smash Down Northwich Town" and "Let's Have a Riot in Latchford."
Police say they infiltrated the Facebook page of Jordan Blackshaw last August and promptly arrested him after no one else joined him for the riot. Sutcliffe-Keenan's page was only up for a few hours before he took it down.
Lord Judge said: "The imposition of severe sentences, intended to provide both punishment and deterrence, must follow."

The violence started after the fatal police shooting of a man in London's economically depressed Tottenham neighborhood and quickly spread to other cities across Britain, terrorizing the country for four straight nights.
