Although I see Kyugima's point, I don't think its generally a good thing for a forum member to scald those when its not really their place to do so, like when the wrong was not aimed at yourself, which is what happens most often.
Anywho, for me, I do prefer 'Floofs' instead of karma, and like Zarago stated to me before, karma is more religious. Some people might feel rather uncomfortable with that.
