Yes, we are.
I recognize the example you described. I've seen that as well. That is one of the challenges, especially immediately after a crisis. We're seeing content being uploaded and they are playing with it a little bit to try to confuse our systems.
What we do, particularly in the case of hate content and violent content online, is to tighten the standards within which we identify videos so that we're taking them down even more quickly.
Even in the context of Paw Patrol, I think your daughter will likely find that if she goes back to the same channel two weeks later, they may not have the Paw Patrol content because it will have been recognized and taken down.
