There's a youtuber who breaks down samples in songs by hip hop artists, and he gets striked or all his earnings taken by someone who stalks his videos, he used to cut samples to below 15 seconds, and still gets striked. You can't even defend yourself, and arguably he is within FAIR USE of the content.
Someone, somewhere is going out of their way to strike their videos. It's ridiculous, do they strike news channels when copyrighted music plays in the background without their control too?
