These two have played alot of games against each other. In 7477245 they have only attacked each other when taking non important areas (about 3 times total). They havnt got any defence at their boarders and they dont break the other's bonus. They have not called anything in the chat, so in my mind ...

Funny I should about to post about those two

But as smartin23 says, they attack at the same time and don't attack each other.
