Agreed, I'd happily run a server but I would need some kind of aggregator service to post my proxy on. Surprisingly enough I don't have many contacts in Iran lol
But, I do understand that it is otherwise difficult to reach Iranians and not hand their government a list of urls to block. But I think my reach is useless. If your reach is not, then maybe you'll also reach the Iranian government easily.
Moreover, should I run this from my personal server? Could it become a target for nefarious stuff? I feel the same as I do when I think about running a TOR exit node. I want to be like my hero Edward Snowden but... I'm afraid of the stuff that gets associated with my IP address.
