I just don't buy it, griefers act in very predictable ways with certain motives and this one just doesn't seem to fit. The griefer would have no way of knowing whether it caused a hassle or not, there's no direct interaction after the kick. There's also the matter of directly involving authority figures which runs the very real risk of getting themself banned if they were indeed harassing anyone in the obvious way described. It doesn't add up, huge risk and little to no emotional payout, it's not a griefer's MO.
