Is this the first country which genuinely effectively is able to ban tor?
Because even in China, tor can work through bridges or some other methods and even Chinese firewalls aren't so extreme as iran right now.
Edit: forgot that north korea exists so I guess the second country but even in north korea there was this chinese interviewer or japanese interviewer who contacted people in north korea ig and those north koreans then interviewed for the first time completely uncensored north korea and it was brutal (a girl saying both her parents died and she was so so skinny i think) , they then went and smuggled the tapes from north korea to china and then to japan and then the company/production company or something blurred the peoples faces involved for anonymity.
There's also this 1 steam connection in north korea so its just gonna be a mystery if we ever see a north korean person using a tor but I am 99% sure that it wont but north korea also got 1 steam connection so you never know.
