"Plus they have no punitive powers other than if you intentionally disrupt a quest to be spiteful then of course your practicing harassment."

Perfect example of why this is a horrible idea. Completely subjective, how do you know if somebody hunts them to be "spiteful"? You can't know. In effect, they have Special Subjective Rules about being hunted and killed that other players don't.

"Regarding killing them, you can as always. If they started a quest while being hunted that would be no different than other abuse. "

This means they can never, for example, participate in PK, castle looting or anything that affects other players, since doing that is the same as "being hunted" in one sense. If they assist in looting a castle, they can't ever run a quest, since, in your words, that'd be abuse.

And furthermore, they're given certain powers that makes them harder to kill. Do you really want admins to waste their time reviewing every possible case of this..?

"I think kim meant not hunting them but if you say looted their castle then suddenly you will never be allowed to get into a quest because of their personal feelings towards you in regards to looting/killing them previously"

Not at all. \:\) See my previous replies.
