As far as I'm concerned it's considered griefing if you're intentionally doing something that you've been asked not to do and the group had every right to vote kick you out of the group. I would do the exact same thing if it was happening in one of my groups, or if an acn/smn had Carbuncle/Garuda on Obey and was using the knockback on cooldown.
