Too many times someone decides to spoil an important part of the novel at the end of a chapter. I think one solution would be the option to turn off the ability to view these comments
Option to turn off comments at the end of chapters chss
I have ran into this a lot too. People have read ahead of the chapter come back and post spoilers. I just got to the point that I don't read any comments at the end of chapters at all.
This, or add a spoiler toggle when posting a comment in the comment section.
