求翻译：But let's qualify: Weibo users only really have access to initially unfiltered information. Like all Chinese Internet companies, Sina, the company that owns and operates Weibo, must maintain its own in-house censorship staff. Part of what they do is routine: ensuring that topics that are clearly always sensitive (critiques of current party leadership; the Dalai Lama; etc.) do not become flashpoints. Part of what these censors do is respond to real-time government directives about discussion topics that have arisen suddenly and are deemed too sensitive, and so need to be contained. In such instances, through a combination of automated mechanisms (i.e., rendering certain search terms temporarily inoperable) and manually taking down content,the censors try to put the cat back in the bag, as it were. This is what happened in the case of the Jiang Zemin rumors.是什么意思？
