Not safe for kids!
My husband and I both delete YouTube apps on our phone because they automatically "recommend" crap/inappropriate programs/ cheap knock offs to our child. And you cannot block all of them because there are just too many and perverts are producing more! Some videos are very subtle and not obvious but if you know Elsagate you know they are just introductory to the real sick ones! Do not take any chances!
