Morocco—Morocco has had YouTube banned because of videos that mock the Moroccan king as well as some pro-Western Sahara clips—until today. For the first time in two weeks, Moroccans can access YouTube again.
Brazil—Brazil, like Turkey, has had a nationwide YouTube ban due to a court order. The offending clip this time was Daniela Cicarelli's sex stunt on the beach (how you can expect to have sex on the beach and not have it end up on YouTube is beyond us), and this Brazilian model insisted that the clip should either be fully removed (and users stopped from reposting it) or that YouTube should be banned altogether. YouTube was banned for a while, but the ban was removed relatively quickly.
China and India—Finally, China and India currently have no active ban on YouTube, but both states have on occasions threatened to block the video sharing website; India because of a video clip mocking Gandhi, and China because of their general policy of banning, well, all kinds of stuff.
