When I apply the statute, my justification is along the lines of "people usually only care about spoilers if they're watching a series or planning to watch it soon, which are unlikely given a random person and a random series". Hariant's comment could easily be interpreted as asking for recommendations of anime to watch, in which case "planning to watch (considering watching) it" would be a given.
We cannot meaningfully discuss how DN & ilk hold lessons for LW without discussing plot events; funnily enough, spoilers tend to be about plots. And as I said, applying the principal of charity means not interpreting Hariant's comment that way.
