It has become so common that it is considered Internet background noise. You won't get a reply from the controlling NOC and you won't stop it because it's a combination of Chinese people trying to get around The Great Firewall and the Chinese Authorities trying to get there first. Just blackhole it, let them hear the sound of one hand clapping and get on with your life.
