Hi. I recently saw the page you created on the Melanie Martinez Wiki an hour or so ago as of the time I'm writing this. While I can see that you were trying to help, such content should probably be moved to the blog namespace to avoid conflict. (Although, I don't exactly know the rules over there...)
Also, I'd recommend changing the first line or two of your profile (the part that reveals your age) to avoid getting reported to Wikia for violating COPPA.
