China Bans Tiananmen Searches on Anniversary of Protests

From Mashable:

Banned terms include “six four,” “23,” “candle” and “never forget,” according to the BBC. Sina Weibo has even blocked users from using a candle emoticon as it’s considered a symbol of mourning. When Weibo users started using an Olympic flame symbol as a work-around, Weibo blocked that as well.
