If you are asking average webmaster whether internet traffic from Iran does any good, most probably they all will say no. This is happen because Iran is being subject of sanction by US government. US companies are forbidden to conduct business with Iran openly, and this makes any traffic come to your site which is persian origin are basically spam, you couldn’t make money from them.
Iran’s government probably watch their internet users, and this makes proxy sites getting popular in Iran (proxy = a site to cloak your ip address, make you anonymous). And to be my surprise, I have some proof that even government officers actually use proxy.
Dunno whether they are using it to access p*rns or anything (see this top adult sites in iran), but still interesting to note:

Iran government using proxy?
as you can see from the pic above, I logged at least one ip address from Iran govenment Office, and it’s actually ministry of education office in Khorasan (80.191.244.88) . And the other one is from iranian research organization (62.60.149.63) located in Esfahan.

Funny. Really peculiar. Do they really use “Adult” as bait to attract traffic ( by horny men I suppose)?
I didn’t really check because there was this question to put off my “safe mode”. Which I think would have been a bad idea.
logically, traffic could made you money because everytime people click ads on your web, you get the money, us and europes are the primary market, while the rest of the world (the third world) doesnt have high value for traffic because most of the advertisers are us/eu based. this makes any traffic come from blacklisted country by US (such as iran, cuba, and north korea) is just a “spam”. most of the proxies used by iranians are to access adult sites, even the ones in government offices.
