Rule 1: Botting
The use of any script/application to play the game for you is prohibited. This includes bots, auto clickers, macros etc.
Rule 2: Multiple Accounts
You are allowed to play 1 account. If you have multiple people playing from the same household then make sure they do not interact in a way that benefits a single account.
Rule 3: Cross Trading
Cross trading discussions should be kept to trade chat. Any transactions that happen outside of the systems in-game are done so at your own risk. Discussions of selling in-game items for real money is not allowed, and will result in your account being permanently muted, or possibly banned.
