I HATE macroers. Mainly the woodcutting bots and shop bots. The woodcut bots kind of steal your logs... ... and the 'shop bots' make it impossible to buy Death or Chaos runes from the shop. HOW AM I SUPPOSED TO TRAIN MAGIC LIKE THAT? :evil:
I usually just ask them why they follow and answer their questions... If they are annoying, beg or follow too long I just go walk near some agressive monsters or the Wilderness :P Or log out or teleport.
