To Iran, as of today, we can browse and login to Battle.net and launcher is also patching. Even in the Account Management section people now can select Iran as their country of residence. Meanwhile Syria and North Korea still aren't there.
But, most of us are scared to actually login to any games at the moment, because we tried to get an answer from them through CS forums and a few people even opened tickets. Yet, the topics in the forums got locked. Some of the tickets were answered with this automated response:
"Sadly Customer Support can not offer any further support with this, we are looking into the situation at present.
Any questions should be directed to email@example.com, sorry for the inconvenience on this."
So, I'm not usually a paranoid individual but, ye know, I feel like I'm about to enter a trap. Especially since they are dodging giving any straight answers, ok just tell us if you lifted the ban or you just want to trick us into some kind of scheme.
