If you are interested in reporting on, or just learning about, how censorship works on Sina Weibo, here are some resources we found useful:

Blocked on Weibo, a book and blog by Jason Ng. They both include a list of words that have been banned from Sina Weibo over the past few years, as well as an in-depth analysis of what the words mean, and why they might be blocked.

Freeweibo.com and WeiboTrends. These sites let you find and read censored posts from Sina Weibo from a pre-selected list of authors.

WeiboScope. Published by the Journalism and Media Studies Centre at the University of Hong Kong, this project also includes a large number of deleted Weibo posts. We selected part of our original sample of Weibo users to follow from WeiboScope’s set.

China Digital Times. While not specifically focused on Sina Weibo, the CDT translates government directives and leaks regarding censorship.
