Weeks after the 18th Party Congress, Sina weibo censors seem to have settled on a new censorship approach to delay in showing sensitive searches . From Feichangdao:
The screenshots below show that, two weeks after the announcement of the new Politburo, Sina Weibo administrators had yet to settle on a consistent approach to censoring information about the Communist Party’s new leaders. At first glance, it initially appeared that Sina administrators had decided to not censor searches at all. For example, in the left-hand screenshots below, searches for “Xi Jinping” and “Li Keqiang” apparently returned thousands of results and there is no censorship notice anywhere on the page. A closer look reveals, however, that all of the “Hot Posts” were several days old, and the posts following the “Hot Posts” were actually delayed by almost exactly 48 hours.
[…] One month after the announcement of the new members of the Politburo Standing Committee, Sina Weibo appears to have settled on a “new normal” – it will impose a one week delay for search results for all PBSC member’s names in Chinese, except for “Hot Posts”. The screenshots below show that the most recent results for searches for “Xi Jinping” on December 13 and 14 are from December 6 and 7, respectively.
[…] The new rule is not only being applied to leaders and their families. These screenshots show that, whereas a search for “Xu Zhiyong” on November 27 returned results from as recently as November 25, the same search on December 18 did not return any results from the preceding seven days (with the exception of “hot posts”).
