The rules seem pretty clear that consent is required from any persons appearing in any external datasets that are required. The winners scraped data from Youtube videos so I am not not sure the issue is.
The more worrying takeaway is that the winners scraped videos from people who clearly had no intention of their videos being used for a deepfake detection algorithm. Yet they did not think of the ethical considerations of using that data (did everyone in the video even have a say in the video being uploaded?). I think Kaggle disqualifying the team is the right move (even if it's a painful one for the winners).
