The problem with that is, the law absolutely demands that the platform comply with any valid takedown notice, so YouTube isn't going to risk having any false negatives (due to internal miscommunications on Nintendo's side, etc.). It's made the responsibility of the uploader to challenge it with a counter-notice, but YouTube makes the process for those far more difficult than what the law says. (YouTube opens itself up to liability if it doesn't put the video back up upon receiving a counter-notice, but it's not like the uploader would be able to sue YouTube for much of anything.)

In this case, the notice wasn't even quoting the right section of law! Is it still considered a valid takedown notice, then?
