A widely read microblog written by the U.S. Consulate in Shanghai on China's most popular blogging site was inaccessible Friday, with a search for the account saying results could not be displayed and "relevant sensitive information or garbage content has been filtered." American officials said they did not know why their social media account with Sina Weibo - which sometimes has cheeky comments on China's thorny social issues - could not be reached, , according to AP. "We're still working to find out why our Weibo page is inaccessible," said Shanghai consulate spokeswoman Wylita Bell, reached by phone. "We are speaking with our commercial service provider, doing follow ups, trying to find out why. We also still hope that we can resume normal operations as soon as possible." A Sina Weibo employee in a department that oversees the microblog site's operations said there could be a technical glitch. "We are not sure what happened exactly," said the woman, who refused to give her name. Attempts to access the microblog were met with an error message that said the account is "temporarily unavailable." The results for searches of the consulate's microblog name were censored with a message that said: "According to relevant laws, regulations and policies... search results were not displayed." The Sina Weibo accounts of other branches of the U.S. government in China, such as the embassy in Beijing and consulates in other cities, were still accessible Friday. The Shanghai consulate's account was known for using playful language that included trendy Chinese online expressions to interact with its Chinese followers. The account sometimes made tongue-in-cheek comments about social and political issues in China. It had more than 80,000 followers. Sina Weibo employs a team of censors who make sure the site is free of personal attacks, pornography, as well as any "illegal information," which covers topics the government wants to keep out of public discussions. Sina Weibo says it reserves the rights to delete posts and freeze accounts for content it deems offensive.
