Resource bouncing

Resource bouncing (also res bouncing, or ping pong) is the obsolete tactic (since what update?) of sending resources to a player, having that player rise in rank due to an increase in Wealth, then the player sending back the resources, and repeating to gain ranks. This activity was commonly considered to be cheating, however it was still commonly participated in, due to the easy rank gain. It was then made almost impossible by specify update having RS only count for resources passed down from class to class.
