It is unreasonable to expect all players to have a detailed knowledge of what behaviors are bugs and what are not when the nature of the bug is such that it is not obviously a bug. IMO, and this is how I will vote as a Magistrate from this point forward, if the bug is not obvious in nature and it cannot be conclusively proven that a player operated in full awareness of the nature of the bug, you cannot punish a player for playing the game as it is presented to them.
If the game allows you to do something, then as far as I am concerned a player is doing nothing wrong by doing it unless the nature of the action is so obviously a bug that the player cannot reasonably have come to any other conclusion about it, and I am inclined to make that an extremely high bar to meet. If a bug exists that is game-unbalancing, then the burden of action is on the developers to rectify it, not on the players to be aware of it and avoid it. Until such a time as the developers take action, players should not be held responsible for playing the game as it is rather than game as it should be.
That is all I have to say on the subject. Please expect me to consistently apply a very high standard of evidence to complaints of this nature in the future.
