"Overall, we attempted to download 130M videos and achieved a link success rate of approximately 60%, resulting in 80M successfully retrieved videos with a total duration of 10M hours."
I am astonished that the success rate is so high. How Youtube didn't block them, I don't know. But I think that this URL list won't age well because youtube will very quickly block any researcher trying to download these videos themselves.
