The resolution however wouldn’t resolve anything. The whole argument in the OP is based on a belief (unsupported by any critical analysis), that gankers gank because it gives them a killmail and that somehow, the level of ganking for that purpose is significant enough that if that is removed, somehow the player count will stop falling and actually increase.
It ignores many of the reasons that gankers gank, that don’t involve just getting a killmail (eg. fun, profit, because they want to play the villain, because the game allows and encourages it, etc.); and the proposed way to resolve the issue that hasn’t shown to be an issue, won’t actually work.
It will still just deny people intel that they can use to help protect themself; and do nothing about all of the other more influential reasons that players gank.
