I guess YT revise the videos with some Machine Learning model, what is translated as such analysis will always have errors. It seems YT ignore such errors existence and delete & ostracizes the affected channel from any kind of human revision, making that YT channel owner to feel a stressful and miserable experience trying to find communication ways for to prove there is nothing wrong in the content.
Be warned, because although today it is YT, tomorrow will be the public administrations that will be using these sloppy statistical algorithms, if its allowed the marketing around ML reign (sold as IA) over the people.
