On Eve of Third Plenum, Baidu Blocking Users From Setting Up Forum on "Third Plenum"

On November 8, 2013, the state sponsored Global Times published an article entitled "Only 33% Want Political Reform at Party Plenum." Some excerpts:

A Global Times poll has found that respondents from seven major cities regard the social welfare and social security systems as the most anticipated areas for reform at the upcoming plenum of the Communist Party of China (CPC) Central Committee.
. . . .
The result of the poll came before the opening of the Third Plenary Session of the 18th CPC Central Committee on Saturday. The four-day plenum is expected to roll out a package of reform plans, with top leaders repeatedly vowing to comprehensively deepen reforms.
According to the poll, more than 63 percent of the respondents said they will pay close attention to the plenary session, while some 36 percent said they will pay no attention.

This screenshot was taken on November 8, and shows that Baidu has banned users from setting up a PostBar (Tieba 贴吧) forum to discuss the "Third Plenum" (三中全会).

These screenshots, taken at the same time, show Sina and Tencent Weibo were not censoring searches for that term.
