If you derive a significant portion of your income from streaming video content, you should probably be using hosting sites like YouTube and Vimeo only to mirror your self-hosted content and drive traffic back to servers you control if you can. You never know when companies like Alphabet or Facebook or Amazon or Apple will pull the rug out from beneath you and yank away that source of income, so don't stand on their rugs. If you let someone stand between you and your money, there will be someone standing between you and your money. And as there is no way they could possibly review all uploaded videos with actual humans, much of this enforcement is done by machine detection and automated processing, and you will never get any explanation from a human, unless you are in the top 1000 accounts ranked by how much money they make for YouTube. Not that this sort of content needs to be in video form, anyway. If I feel the need to learn about new, unregulated, or misregulated drugs, I'd prefer reading text, with as few still images as is possible to convey the needed information.
