This is a massive problem on YouTube right now. Essentially, there are a few large troll operations that abuse Google's "Content ID" system to steal ad revenues from random accounts, while Google shows no interest in fixing the system or shutting down the fraudulent accounts. The targetted videos often contain original music or no music at all. It's so common that it seems to be a fact of life for anyone as soon as they start monetizing their videos, and it's enough to remove any desire I have to do business with Google.
