This assumes that everyone and their dog just immediately whips out 20 5kers and flies in formation, and nobody sees that and thinks "boy oh boy, piracy time". For every play, there is counterplay, and activity generated = people logging to react to activity. Sure, when your convoy makes it, big bucks. But your convoy has to make it.
In a vacuum, multiboxing would be bad and a clear-cut unfair advantage. In an environment where players can damage other players, I believe the risks ultimately outweigh the rewards.
