For me the spoilers I don't like are leading ones where it leaves you open to wanting to know whats next, if it just states my curiosity, like lets go the duchess in the attic, or whatever its name is, where the manga is monthly, and the ln is far enough ahead that you can know what happens, for the last 4 months I have had a relatively good idea of where there story goes for the part i'm interested in, and that's enough, now the manga just lets me watch it play out.
another way to put it is wiki movie plot synopsis, unless it's a thriller or mystery where not knowing is the best part, I get as much watching the movie as I do from reading the plot, hell much of the time I read the plot before I see a movie and I miss nothing, it just saves me money on movies I don't need to see.
