The tin-foil hat is unnecessary. What you describe is happening, all the time. It's not even perjury. I was going to describe things that falsely take down videos as "perjury-bots" but then I remembered that major sites such as YouTube and Twitch have set up their own expedited process outside the legal system. They'll even find the content for you. You just have to say "This sound/video is mine, whenever it appears", and when a sufficiently high percentage of sound and video actually are yours, organizations will believe you whether or not it's true. So large content companies just claim everything they possibly can, regardless of whether they're allowed to or not. It's all upside (more revenue from videos!) and no downside (nobody will hold you accountable).
