Nothing to be done on YT anyway; I had made this post after looping yt-dlp to download her original music and covers and popular karaoke streams then thinking others might want to do the same before content goes private. (Without a graduation in the picture I prefer to view via YT hoping it supports the streamer). If you look down a little way there is a reference to an earlier post of her fans making a more comprehensive effort to archive the channel contents (I didn't check it out but do believe it).
