YouTube Chinese interference ?

I would suggest reporting that channel that you are viewing in YouTube as not being a legitimate stream.  YouTube has thousands if not hundreds of thousands of channels/streamers that they have to keep track.  There are a number of those that are not legitimate, and they get removed and pop up again later or as a new channel. Those illegitimate ones try to do different methods to avoid detection, including sliding in a different thing in the middle of what looks like a regular broadcast.   If you report it as an illegitimate stream, they will be able to review and remove the illegitimate ones and hopefully get the problem under control or at least be able to put a dent into those broadcasts.
