This is gonna blow your mind but we actually do mark spoilers. I've been here for a damn long time (too long) and I know that after every update, all discussions about the update are hidden in spoiler tags.
Been lurking since like v0.18 I think, and I still think that this thread about this game is only the thread to use spoiler tags so often honestly.
We do not spoiler-tag content from 1, 2, 4+, etc years ago because that would just be ridiculous.
it's really like a book that's been out for 1, 2 ,4+ years like you said, you really can't expect the main thread of discussion of a popular(popular? is this game even popular idk) visual novel and not have people discuss about the latest details, espeically on a day near update release day, people want to guess what happens based on the previous update, people like Moonflare want to talk about their latest crackpot theories(never seen someone so gung ho about their idea more than Moonflare) and most of people, people love here love to share and talk about everything about this game; it's a bit unfair to expect everyone here to be hush hush about what their favourite scene was or their favourite character did and how it defines their character growth, including our protagonist.
Random question btw, unrelated to all this
If Moonflare's ultimate crackpot theory ever actually becomes real, do we call them the Lessons in love prophet or the second coming of selebus?
