Rather then make a bunch of changes people hate to stop real world trading how about doing somethings that cause problems for autoers this will atleast keep people from using the autolevelers to up their account. add bunny rabbits to the game that take advantages of glitches in the cheat similar to the ones mentioned on this sight about wearing certain color clothes. Most players the bunnies would effect no more then squirrels do now. Bunnies would just hop around everywhere and cause people to follow them. For example if you had an autominer in the dwarven mine south of the black knight castle a bunny rabbit might cause you to chase him to lumbridge running there so you are out of energy and have to walk to get back to a mine. :)
