Epoch Times reported that, in an effort to justify the forced use of Internet filter software, China used faked evidence against Google and even shut down Google China for a few hours. On June 18, the host of the popular prime time show, “Focus Report,” on state-run CCTV demonstrated that a large number of pornography terms could be found in a Google search. On June 25, network traffic analysts found that a week before the CCTV program, some people had deliberately searched lots of pornography terms on Google. The daily pornography terms search rose 5950 percent, in a linear fashion as opposed to a smooth curve that would occur in normal situations. Those searches came from Beijing. Netizens also found out that the student who appeared on the "Focus Report" program accusing Google China of linking to pornography information was actually an intern for CCTV’s “Focus Report” program.
As a result, Google was forced to stop the suggestion and translation features on Google China, which had given it a competitive advantage over some other search engines operating in China. Those features also made it easy for individuals inside mainland China at least to see links that the government had blocked. There is also a report that Google China agreed to install server filtering software (the so called server version of the "Green Dam" filtering software) on its servers.
