Very few people would take a bounty on an Admin as they have various versions of the Gunganiser which they get to use from beyond the grave! may even be an Ewok version too :p
Don't kill the admin, save the kittens! Most the admin are nice, except Avid Soyak, who thankfully is gone. My advise to you is to go to Squall Chitose, try to buy my npc and beat me up. it'll make you feel loads better.
