That type of scenario is why the rules are an unintelligible instrument for administering the game currently. Like the tax rules, they try to cover every imaginable possibility and they assume every person playing the game would cheat if they could.
There is probably a definition of accidentally in there somewhere, and if there isn't, there will be by 2019.
As long as people play within the spirit of the game, such problems shouldn't arise. And those who do not play in the spirit of the game will play by themselves, and be playing with themselves.
