IBM said Thursday it has developed a system for a Chinese mobile phone operator that blocks spam text messaging, but denied the software could be used as a censorship tool. The US software giant said the system had been developed for a subsidiary of China Mobile, the world's biggest telecom operator.
"The anti-spam texting system IBM developed for Fujian Mobile is solely designed to improve the performance of telecommunications networks by blocking high network traffic associated with spam SMS activity," IBM spokeswoman Harriet said.
