The ban is fair, I also personally banned MKs.QarZ for this very same reason.
The feature where you are able to have a bird's eye view of the spawn point before you spawn technically requires that you are alive and that your player is in the vicinity of the map somewhere. That's how you're able to see everyone in that area.
When you're in this state, we place everyone's body inside buildings where no one can reach them and no one snooping around for bugs should have noticed them. To my horror I'm there AFK for a moment on that same Prawn Island option, seeing QarZ running a train effectively stats padding. I don't really think it's coincidence that it's Night Wolf members perpetuating this idea either, some conversation took place for the members to be trying it, to effectively rake in easy sprees and stats pad. You guys know what you were doing and why you were doing it, this abuse is a serious offence.
The bans will remain. Anyone else that so happens to practice this exploit will suffer the same fate.
