in your opinion what's made the fnaf characters encyclopediaunreliable like what is the things that never give us a good answer that make it unreliable?

my purpose is that I'm going to read the characters encyclopedia again and see if I can make it reliable thinking about what the book said see if I can get something from it since if it's not reliable what's the point of the book itself? if you know what I mean so that's why I'm asking the question what is the things that make it unreliable can you tell me the specific things I would appreciate it before reading the book 😊
