Why can't the “great Chinese firewall” stop outgoing spam?

Everyone knows about the “great Chinese firewall” - a filtering system for unwanted foreign websites that are not available for viewing from the territory of China. At the same time, few people know that the same system is also used to block certain Chinese websites from access from outside, that is, from abroad. These propaganda resources are exclusively for “domestic consumption.”

In this regard , a completely natural question arises : why are such large malicious servers from which malware and spam is sent all over the world physically located in China ? The analysis shows that China ranks first in the world in generating malicious traffic.

The effectiveness of the Chinese firewall raises some doubts and is the subject of ongoing discussion. Distributing gigabytes of spam and viruses from China is another argument in favor of those who speak of the inefficiency of the firewall. Otherwise, it remains to assume that the "holes" in the firewall are left with the knowledge of the Chinese authorities. If we recall the recent news that almost the state brigade of hackers began to form in China to wage an information war, then it is quite possible to believe in the version of the deliberately “full of holes” firewall.
