This might be peripheral to the main point, but I have a hard time believing this. Spurious takedowns have inspired multiple waves of invective on YouTube alone. It's a pretty common opinion (at least in my circles) that the current law unduly encourages copyright owners and their representatives to send vast numbers of notifications with no regard to their accuracy. Furthermore, the lopsided requirements of notification vs. counter-notification ("reasonably sufficient" contact information vs. name, address, and phone number) have been abused in order to dox people [1].
