The Pakistani government has banned access to YouTube due to anti-Islamic videos being posted on the site by various users. The entire site, and not just the offending users or clips, have been blocked until further notice. The Pakistan Telecommunication Authority urged users to write to YouTube to take down the videos, but unless they do, YouTube will remain blocked.
Turkey also blocked YouTube in January in the face of a film that insulted the country's founding father (it's illegal to do so in Turkey). And it doesn't end there — both Thailand and Morocco have banned YouTube because of videos that were critical of their countries' leaders.
It seems so unfair and misguided for YouTube to suffer as a host rather than the actual videos and users that spurred the banning, doesn't it? I can't imagine being blocked from my favorite websites by my government, so it goes to show — don't forget to vote.
