Fantastic adventures was a YouTube kids channel starring 7 adoptive children who made skits on various topics. They had 800,000 subscribers before the controversy. News broke out that the mother who adopted the seven children abused them. The channel was terminated by Youtube on Wednesday of that week. That leaves almost all the videos lost, but some were archived before the channel was terminated.
