Well, the way I see it, there will always be some people offended if you do anything, because:
A. there are too many nuances of too many people to anticipate all the things that might push somebody's button
B. people will always assume the worst of your motivations unless they already consider you a friend (this is not my low opinion about the Ryzom community, this is a psychological fact about all humans; you can look it up)
And that's why intention is the only usable criterion for griefing that I can see. Yes, in theory, this means someone could grief and then get away with it by claiming they really had the best of intentions. But I'd rather some get away with griefing in this way, then that we're constantly on a witch-hunt looking for any actions that we might interpret as griefing.
