On 19 and 20 May 2010, Pakistan's Telecommunication Authority PTA imposed a ban on Wikipedia, YouTube, Flickr, and Facebook in response to a competition entitled Everybody Draw Mohammed Day on Facebook, in a bid to contain "blasphemous" material The ban imposed on Facebook was the result of a ruling by the Lahore High Court, while the ban on the other websites was imposed arbitrarily by the PTA on the grounds of "objectionable content", a different response from earlier requests, such as pages created to promote peaceful demonstrations in Pakistani cities being removed because they were "inciting violence". The ban was lifted on 27 May 2010, after the website removed the objectionable content from its servers at the Demand of the government. However, individual videos deemed offensive to Muslims that are posted on YouTube will continue to be blocked.
