I am not sure you want to stare down the Iranian justice system.
Tbh tho, I wouldn't be surprised if you setup an Iranian site that you weren't accused of "funding terrorist operations" and the trial gets replaced with a US drone strike.
Point taken, though.
As in, you live somewhere else out of reach of the Iranian and US justice systems. But you host the site in Iran.
The point is where isn't important. Given a large enough market, the US would do whatever was needed to catch you. :P
