IFlyTek is portrayed in the Chinese media both as a technology innovator and as an ally of the government. Last year iFlyTek helped prevent the loss of about $75 million in telecommunications fraud by helping the police target scammers, according to The Global Times, a nationalist tabloid controlled by the Communist Party. Its article quotes a Chinese security official as saying collecting voice patterns is like taking fingerprints or recording people with closed-circuit television cameras, meaning the practice does not violate their privacy.
Does your raw access log display a host name of “0”, or zero? Very odd, is it not? I have been struggling with this for a couple of months, and my ISP Site5 had no answers. It turns out that one of my spammers, NFORCE_ENTERTAINMENT, puts an unprintable character into their host table, so that when my ISP looks them up, they display the unprintable character in my log as “0”.
Trying to control your site’s spam can be challenging. If you try to ban an IP that is simply 0, or a host name of “0” you will fail, because there is no zero in their host name, but an unprintable character. Ban these guys instead.
