Youtube, Facebook and company have a ridiculous amount of false positives, for the money (and the people, they have quite a lot of human moderators) they throw at the problem. Also, they enjoy complete market dominance, so even if you want to move out of youtube... where are you going to go?

With the same rate of false positives there will be enough community rage (I guarantee someone is going to find a way to have your system ban the top 10 streamers of your game after 2 days you put it in place) your players (both good and bad) will go somewhere else. :)
