If you are hated by the Steamwheedle kartell, you gotta love this. It will grind your rep back in a pretty short time. It basically runs around on two of the ships, south of BB and kills stuff Its a questbot profile Dont cry if its not ferpect; I am a noob! Added a profile for Tanaris; killing mobs in the Pirate area.
Oh yea, you can also use it to grind for one of the rarest pets ingame: http://www.wowhead.com/item=8494/parrot-cage-hyacinth-macaw
