All may seem fine, but i have noticed that some friends that have not used macros at all are even banned. One person got banned for advertising a site (all he said this drop was supported by ~~~), one got banned for no known reason, another got banned for going into the wild and burying 1k big bones, and one other got banned for something which i can remember (but it was a repedative task). Although it may stop troublemakers, it is almost like an abrasive sanding over the wood of the game.
