In English: if a creator does not label AI-generated content when publishing, the platform labels the undeclared content from its own detection and limits how far such unlabelled content is shown.)
What each platform lets you say
Rules have been read for 6 platforms. Every line is the platform’s own wording, and a cell that hasn’t been read says “not read yet”. For another 21 platforms we only know what kind of place each is.
