I can see where you're coming from on this sangwa, I myself had to think on this, I would define spoilers as showing spesific words to quests, and items you recieve from them... IE: how to get lightening glyph!, how to get energy glyph!, meteor, etc etc... However there is a difference between information and spoiling, I believe. I think maps can be helpful, as can which npcs loot certian items, and where the locations of mines are, tips on dueling, what potions do what... those things are helpful to a guild, but again, if ya ask me, a spoiler is giving away quest information.
