I would like some clarification. This forum says plainly, no spoilers; but many people post spoilers here, some very minor, some not. So my question is are they allowed here or not?

 

Also, what constitutes a spoiler? Does merely mentioning a character or game location count as a spoiler or only plot points?

Well, there's a lot of people posting wherever they like. We try to move & spoiler-tag things, but we can't deal with it all. 

 

It's just a general rule - e.g. nobody wants to be surprised by a thread discussing the ending, so it's a common courtesy. If in doubt, spoilertag it. If your whole topic is about something specific that happens in Act 3 or whatnot, go to Stories or Gameplay forums.
