Here is another For the Record moment: For the record, most games do not specifically intend to operate like this (this being grudge's above post). Some games do, like this one. Most games with binding diplo don't tell you to post NAPs on the forum though. So if you do this in a normal game, don't be surprised if you're the only one
. Even if you do that though, it could be awfully hard to prove that the person actually attacked you without ending the NAP properly first.
