Well, apperently, there's this creepy thing called"Username666" and what you have to do is go to the search bar on Youtube and type in 666 and refresh the page then there's this thing happens where your Youtube homepage turns all devilish and then theres this video you go to and its this devil face and you cant exit out of it, i don't know if this is true or just fake, But to avoid ban, DO NOT do this, if you do it i don't take blame of it
