Baidu Tieba was released to the public around December 1, 2003. as well as its campaigns to flood/spam rival Tieba bars Tieba became notable on the Chinese internet for its numerous controversies. In 2017, Baidu Tieba was investigated by the Beijing Municipal Cyberspace Administration because users were allegedly using it to "spread terror-related material, rumours and obscenities". It has previously been summoned by the Ministry of Public Security for concerns including "inadequate security management and prominent issues such as illegal information involving firearms and explosives, the sale of citizens' personal information, and pornography". In 2018, a man used Baidu Tieba to solicit a
hitman for an unsuccessful plot to murder his wife. A 2025
Vice News article stated that Baidu Tieba "was often used for criminality", while a 2021 journal article stated that Tieba was known as a place where "victims can share their experiences of being victimized and warn other potential victims". Baidu Tieba began to decline in traffic beginning in 2012. By 2019, its traffic had declined substantially relative to its heyday, having only tens of million rathers than hundreds of million of active users, with other platforms like
Weibo,
WeChat,
Douyin,
Bilibili,
Xiaohongshu and
Zhihu having gained prominence. By this time, the homepage of the website was "dominated by advertisements and live streams". On May 13, 2019, topics posted in Baidu Tieba before January 1, 2017 were hidden. By 2021, it had lost nearly 90% of its userbase compared to 2015, down to only 37.43 million monthly active users. This decline has been attributed to several factors, including competition from rival platforms, heavy-handed moderation by Baidu administrators, excessive demands of volunteer moderators (who at one point were demanded by Baidu to fulfil "a 2% daily increase in daily forum visitors, a 3% daily increase in the number of new topics, a 5% daily increase in the number of replies, and a 1% daily increase in check-ins." in bars/forums they moderated or face removal from their moderator position), and excessive commercialisation. ==International development==
