CHINA-IRAN Domain Trading #225

Dear Chinese friends.

In Iran, we're facing domain filtering upon the detection of our VPN. Therefore there are many blocked domains which are useless among Iranians. I suspect a similar situation is happening in China too. The domains which are blocked in China could be used in Iran and vice versa.

I was wondering if someone in China wants to trade blocked domains.


亲爱的中国朋友。

在伊朗,我们在检测到我们的 VPN 时面临域过滤。 因此,有许多被封锁的域名在伊朗人中毫无用处。 我怀疑类似的情况也正在中国发生。 在中国被封锁的域名可以在伊朗使用,反之亦然。

我想知道中国是否有人想交易被封锁的域名。

There is something about cross-censor blocked domains in MassBrowser (previous thread here). See Section III-C:

To demonstrate the extent of usability of client-to-client proxying, we use the measurement data provided by ICLab and GreatFire. For each website, we compute the number of countries that the website is blocked in. As shown in Figure 2, the majority of censored websites are only blocked in one or two countries. This is specially more apparent for political and news content, as censorship rules on such content are heavily dependent on geographic regions. Therefore, an Iranian MassBrowser client can help a Chinese MassBrowser client to access webpages blocked in China, and vice versa. Figure 3 illustrates the intersection of blocked domains in three major censoring countries of China, Iran, and Turkey. We believe that using clients-to-client proxying is a major step towards balancing the ratio of circumvention proxies to circumvention traffic, and therefore improving circumvention QoS

You might consider getting in touch with MassBrowser and ask how they prepare their lists.
