Earlier quoted context omitted.
Unless I go to china, download the app on a chinese phone and use it, I cannot see for myself.
You could easily see for yourself by visiting the link in the previous comment. For what it's worth. Four out of the first five videos I saw on Douyin were sexualised in some way, the first was of a train driver. I scrolled through 20 or 30 of the videos on TikTok's website and didn't find anything close.
It's not proof of what is being claimed, but they are variables that would need to be controlled before being confident that Douyin is or is not adjusting content to foreign or domestic users.
