World Forum

First, it doesn't mention China (or anywhere else that Facebook is completely blocked). I'm not sure which other countries have a complete block on Facebook other than China. I lived in China in 2011-2012 and had to use a proxy to be able to use Facebook.

Second, most of the censorship has to do with criticism of governments. There are other countries where libel laws are fairly strong (like here in South Korea) that content could be deemed damaging to the government.

Third, I think Facebook should send Chilling Effects every request for censorship. It should be public knowledge if a government is forcing the removal of information.
