Sina Deletes Taiwan Politician's Weibo Account, Baidu Censors Related Searches

A Baidu search for the title of the Nandu article
returns no results, just a censorship notice.

On February 20, 2013, the state-sponsored Nandu Net (南都网) published an article entitled "Former DPP Chairman Frank Hsieh's Weibo Shut Down One Day After Verification" (台前民进党主席谢长廷微博认证仅一天被注销). Some excerpts:

Frank Hsieh, former Chairman of the Democratic Progressive Party, opened a Weibo on mainland China's Sina web site, becoming the first heavyweight figure under the Green banner to open an account from across the straight. He accumulated over 50,000 followers. One Internet user spoke frankly: "Xie Changting has come to test mainland China's bottom line on expression." Shortly thereafter, after only one day of its real name verification, Hsieh's Weibo account was quickly cancelled. The actual reason remains unclear, and its being widely discussed amongst Internet users.
民进党前主席谢长廷在中国大陆新浪网开设微博，成为首位在对岸开微博帐号的绿营重量级人物。累积粉丝数达5万多人。有网友直言“谢长廷是来测试大陆言论底线”。然而随即，正式实名制仅一天，谢长廷的微博账号立即被注销账号。具体原因仍然是个谜，网友议论纷纷。

Here are two of Hsieh's Weibo posts:

Constitutional government is a global trend, so most major countries all have constitutions, but in some countries the constitutions are only used during exam time, and are not actually implemented. Some countries only implement a portion of their constitutions, and typically the portions that are not implemented are those that impose restrictions on the government. This is the source of people's suffering.
宪政是世界潮流，所以大多数国家都有宪法，但有的国家宪法只是考试才用，并没有实施；有的国家只实施一部分，而没有实施的通常是限制政府权力的部分，这是人民痛苦的来源。
Whether or not there is freedom of speech is not a matter of looking at whether one has the freedom to speak in criticism of official power, but whether after one ha finished speaking one loses one's liberty.
有没有言论自由，不是看有没有批评高官权势的讲话自由，而是要看讲完话以后有没有失去自由。

On March 27, China's state run media reported that when a reporter asked about Hsieh's account being shut down during a press conference, Fan Liqing (范丽青) spokeswoman for the State Council's Taiwan Affairs Office replied: "We have said repeatedly that, with respect to the Internet, mainland China has relevant administrative measures, and everything is handled according to laws and regulations." (我们曾多次讲过，对于互联网，大陆有相应的管理办法，一切依法、依规办事)。

This screenshot, taken on February 21, shows that Baidu had banned users from setting up PostBar (贴吧) forums under the heading "Frank Hsieh."

This screenshot, taken on March 6, shows that Baidu had banned users from setting up PostBar forums under the heading "Taiwan."

These screenshots, also taken on March 6, show that, while Baidu was returning apparently uncensored results for searches for "Frank Hsieh," it was restricting search results for "Frank Hsieh Weibo" to a white list of about a dozen web sites controlled by the central government and the Communist Party.
