That's why I only listed the 3 turn limit rule for Alliances. Maybe we should up that to 5, to indicate its significance in relation to NAP's.
See the first post for the current 'rules'. NAP's are only binding if they're made known publicly here in this thread. Any secret agreements are at your own risk.
I've seen NAP's been signed with a specific turn count right from the start; say player A and B agree upon a NAP-5. This means, afaik, that for 5 turns they will not attack or otherwise harm eachother (including economic harm). After 5 turns it ends and it should be renewed by both players to keep it intact. Now, if this agreement was registered on the forum it is binding. If it is not, they're on their own when one decides to backstab the other.

Of course there is no game system in place to limit players from doing stuff to other players even when we say here those agreements are binding. But there is no way to counter this anyway. Like Grudge said, people will remember.
