Excluding Youtube, there’s thousands of cases of fraudulent C&Ds sent to private parties every year. The thing is, for the perjury to get brought up, you’d have to win in court against the fraudulent claim, not settle out of court, and basically be a test-case for this.
The Youtube channel TheBibleReloaded is currently suing a production group (the Christiano brothers) who try to keep censoring them on Youtube with fraudulent reporting. So Youtube’s arbitration isn’t bulletproof.
