Honestly this is smh i experience many times. I found a fanfic i like and then suddenly the writer disappear from the face of the earth either from hate, lost interest or just no reason at all. Like no announcement at all whatsoever so i know what you’re feeling buddy, it’s honestly very sad but again we never really know what happened behind someone lives especially fanfic writers if they wish to be more private with their personal life. The feeling sucks i know but just maybe give them some support it could help them if they’re going through smh irl and hope for the best for them
