On the community I have no idea, but I imagine the next reincarnation of these type of markets will have to be managed by lone wolfs out of a cave in Afghanistan.
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
