Enough of them to give rise to the term "algospeak" which means using words like "unalive" in place of "kill" to avoid automated censorship.

Meanwhile you can report a bot who's posted 20+ comments under a video to advertise illegal drugs and all of the reports and subsequent appeals will consistently come back as "No violation found".

On WeChat lots of things are censored, almost keyword based. E.g. a building collapses, you want to talk about it to your friends, your message can't be sent because it'll be deemed to be trying to cause social unrest..

Duoyin (Chinese version of TikTok) would definitely not be different..

On WeChat and Douyin (chinese tiktok), good luck mentioning things like:

the cultural revolution famine the great leap forward Taiwanese independence Hong Kong self governance democracy human rights Falun Gong Uyghur people free speech KMT party Chiang Kai-shek

and that's just off the top of my head. there are likely hundreds of others.
