All Fright night did was read off of this post https://i.redd.it/uuz3n3xnz9z21.png This post is also from 4chan (it was just re-uploaded to Reddit.) If you go back to the video you can hear him read off of it word from word. So no he did not make up his own content and no we are not copying him. Frankly all we have to blame in this situation is the original 4chan post for the concept of levels, and not some "Narcissistic Youtuber."
I agree but the problem is there are too many people who replace other people's ideas with their's and it creates a situation where nobody can agree what is cannon, and then you have people trying to get rid of "non cannon" content which doesn't allow "cannon" content to form. We just need a good system to decide what is cannon and how we can prevent others from deleting good ideas.
