It seems that the online gaming outfit Blizzard has banned itself from Iran. After patch 1.04 for Diablo 3 and server maintenance, gamers in Iran suddenly can't play any of the Blizzard games they paid for.
According to the online forums this includes Diablo, WoW, and Starcraft 2. A rumour started that the Iranian government had banned the games claiming that it promoted “superstition, mythology, violence and the women were dressed inappropriately”.
An Iranian reader said that probably is untrue. He contacted his ISPs and traced the IP and it turned out the problem is with Blizard and only happened after the server was reset, by the software company. One of the biggest problem is that Blizzard is not telling anyone anything.
