we conduct a large scale randomized experimental study by creating accounts on numerous social media sites spread throughout the country, submitting different randomly assigned types of social media texts, and detecting from a network of computers all over the world which types are censored.
…we supplement the current approach of confidential interviews by setting up our own social media site in China, contracting with Chinese firms to install the same censoring technologies as existing sites, and reverse engineering how it all works.
Our results offer unambiguous support for, and clarification of, the emerging view that criticism of the state, its leaders, and their policies are routinely published whereas posts with collective action potential are much more likely to be censored.
We are also able to clarify the internal mechanisms of the Chinese censorship apparatus and show that local social media sites have far more flexibility than was previously understood in how (but not what) they censor.
An experiment in the narrow sense and the grand sense of the term. Bravo.
