That is definitely the endgame for cheating. I know in WoW, they explicitly ban hardware input broadcasting for multiboxers yet actually detecting that can be quite difficult. At the end of the day, we are trying to find technological solutions for social problems. What I think would really help would be to decrease the ease of duplicate account creation for services which care about cheating. Without that capability, punishing cheaters socially (i.e. bans) is never going to be particularly effective. I think social solutions can work because you don't need to stop 100% of cheaters like some people seem to believe. All you need to do is prevent enough cheating that people believe the game is honest overall. Locks only make sure honest people stay honest, but that actually works pretty well since most people are honest.
