Chinese censors have got so good that they can intercept and edit your mobile calls on the fly.
According to the New York Times, a Beijing entrepreneur, discussing restaurant choices with his fiancée over their mobiles quoted the phrase "The lady doth protest too much, methinks." The second time he said the word "protest," her phone cut off.
Others have reported the same thing. Words, in whatever language, are being used to cut off calls.
Observers think that Chinese authorities are obessed about policing mobiles, electronic messages, e-mail and access to the internet as they try to kill off antigovernment thought crimes.
But several popular VPNs which have been used to bypass the government's censors have been crippled.
WiTopia, one VPN provider, said that it was suffering from "increased blocking attempts" although it did not identify the government as reponsible.
However it seems that the government's computers, which intercept data and compare it with an ever-changing list of banned keywords or websites, are shutting out more information.
Apparently you are most likely to be banned if you use the English word "Freedom" so we guess this article has not made it past the Great Firewall.
