spam...a post that someone places in a thread that doesn't really belong in the discussion, for instance say we're discussing star destroyers, and someone comes in and asks what everybody is having for supper. that's spam, usually I don't crack down on that kind of spam, unless it's bothering the people in the discussion, but if the person wasn't in the discussion in the first place, they didn't add anything to the discussion, so they don't really have the rights to be doing that.
As for threads, well, to put it lightly, the question you asked looked like 2nd grade material. second, the thread's topic was somewhat misleading.
I hope that answers your question.
Battle is a pure form of expression. It is heart and discipline, reduced to movement and motion. In battle, the words are swept away, giving way to actions-- mercy, sacrifice, anger, fear. These are pure moments of expression.
