"Fair usage" refers to a set of rules for how you can use Aion.

Your Aion membership is personal and for you alone. This means it is your responsibility to make sure nobody else uses your membership, and that you don't use your membership for professional or commercial purposes. It also means that when you open an account with us, you agree not to abuse our services, or anything that could cause harm to us, other members or anyone else.

If we think you are breaking these rules of "fair usage", we may restrict, temporarily suspend or indefinitely end your membership and contract with us. The course of action we take will depend on how serious we think your actions are, and we might not give you prior warning of our decision.
