I would say it's unfair because, if he agrees to a no kill agreement, and then somebody else is tp'd over to kill them, that is definitely unfair and could be used all the time as a way to dodge the no kill on tpa rule so that you can easilly kill someone with a friend when they come and split the stuff 50/50 or whatever. Since this is dodging a rule, and he was under a no killing agreement, this will not be allowed. Tob knite will return your stuff ingame whenever.
