"It seems that America and the United Kingdom aren't the only countries caught in a sudden desire to become authoritarian. Pakistan is blocking websites that they feel either will pervert their citizens culturally or politically. YouTube recently made the list for both reasons. There's plenty of sketchy X-rated material on the website, and it's cousin, X-tube. However, it's more likely than not that YouTube was blocked in Pakistan due to political footage. To be precise, someone managed to sneak proof of election fraud, in video form, onto YouTube. Pakistan obviously doesn't want anybody to see this, so they bury the video. When it comes bouncing back later, Pakistan got mad and completely blocked out the site."
