Griefers never understand why the people being griefed hate them so much. It's like smokers not understanding why non-smokers are so disgusted by them. What? I was just having a lark. It's not like I'm doing anything more than messing with pixels, right? You should enjoy my mischevious creativity as much as I am! All I can say is that if you know you're in a group that does griefing as a group activity and group agenda, you deserve what you get.
