Douban

Douban has attracted a large number of intellectuals who are eager to discuss social issues. This makes Douban vulnerable to censorship by the Chinese government. Douban reviews all content posted on the website, preventing some material from being posted in the first place, and taking down other materials after the fact.[6]

In March 2009, Douban removed art paintings of the Renaissance on the grounds that they contained 'pornographic' elements.[6][7][8] This led to a campaign called "Portraits: Dress up" in which internet users were asked to dress up images of famous renaissance nudes in a protest against Douban's self-censorship. The administrators then removed the discussion about the campaign.[6]

That year also saw the 20th anniversary of the 1989 Tiananmen Square protests, and Douban further extended its keyword list to ban any terms that are likely to relate to the incident.[9][10] One example is the ban on mentioning Victoria Park in Hong Kong, the venue where the memorial gathering for the 20th anniversary was held, in the fear that it may lead to sensitive discussions. Users also found that some discussion groups, like the Hong Kong cultural study group hkren, were suddenly banned and all topics were removed without any notice. This angered some members, causing them to move to other similar websites that employ less strict self-censorship policies.[6]

In 2011, some Chinese lesbian, gay, bisexual, and transgender (LGBT) groups announced that they planned to boycott Douban, as their posts announcing an LGBT-themed film festival had been censored by the website. In mainland China, films and television programs with LGBT themes are subject to state censorship.[11]

Douban has been accused that many users of Douban purposely give The Wandering Earth, a 2019 Chinese science-fiction film, one star. Critics further accused that some users "change their given five stars to one star" and some users are paid to give one star to the film, which later turned out to be false. On 12 February 2019, Douban officially announced that "Mass score-changing is abnormal and it won't be counted in the total score. To avoid such incident, we are urgently optimizing product features." in its official Sina Weibo account.[12]

Douban bans on the accounts if they think the accounts are posting ads. The website login by verification code from the registered phone. If the account is banned from Douban, then this account no longer can login.
