why do u think only orkut is blocked in UAE considering the fact that all the social networking sites are in a way or other being misused to promote dating, pornography and everything else, which falls under 'Prohibited Content Categories' of the UAE's Internet Access Management Policy ?!!!
i checked 4 of social networking/group sites and so far i could not find orkut being misused to promote 'bad' contents to an extend what other similar sites like yahoo groups, msn groups or facebook are used to promote the same.
not sure if there was a debate on this before. if yes, please point it to me.
