With the exception of when someone is simply clarifying a detail which a chapter presented confusingly, spoiler boxes should be mandatory when referencing any significant details not fully expressed within currently released chapters (such as the details one may provide when making light novel references), especially when those details relate to future events.
One could maybe even be able to argue in favor of using spoiler boxes for any especially significant plot twists/progressions within the current chapter [though, as you noted, what
else would we be talking about in these comments other than those highlight moments?] but this is the first time I've seen someone get on someone else over that individual literally discussing the weather. 🙄
I mean, if weather forecasts are spoilers, I have to wonder what other mundane details would be. Would it be a spoiler to compliment a character's hair style change? Or to comment that the food they're eating looks tasty? Is it just that we can't talk about any detail, no matter how minor? If so, should we just wait until the next chapter releases so we can discuss the previous one? This just feels as though it's getting needlessly complex, and for reasons that don't make much sense given the structure of the site [it isn't as though we're forced to see comments before we read, after all].
..speaking of, why are all the hair styles in this manga so bland? Aren't manga protagonists supposed to have crazy hair? Is that not
required?
