Account Sharing is when multiple people share a single RuneScape account. This directly violates the 'Buying or selling an account' rule under Honour, and the punishment for all parties involved in sharing accounts is generally a permanent ban. Account sharing is unfair because it allows an account to train and be used more often than a normal human's schedule and free time would allow, enabling the account to move up quickly in skill levels and hiscore ranks and accumulate large amounts of money easily. Shared accounts are sometimes mistaken to be macros.
