After being published on my channel for over two years, YouTube put a strike on my channel for my video showing people how to set up Jellyfin on their NAS, for promoting "dangerous or harmful content".
Video was posted here (https://www.youtube.com/watch?v=4VkY1vTpCJY) and had nothing about bypassing DRM, stealing content, or bypassing subscription services (other than a call to stop using Netflix, Disney+, etc. because they keep jacking up rates while providing less quality).
