As someone who has been writing fanfiction for 11 (almost 12) years, I’ve had my fair share of love and negativity in the comments. Nobody requires you to read it, nobody prevents you from ditching a book you don’t enjoy. There’s nothing that forces you to engage with a piece if you don’t want to. If you don’t like it, don’t read it.
Quit leaving rude comments on someone’s hard work that they chose to share with you; I’m not talking about constructive criticism or pointing out typos, those are totally fine if the author welcomes them.
Just please be kind to each other, especially across a digital screen.
