Some other examples of games with spy on the other team "against" Shaun850 and sdh. The usual profile is that spy doesn't do very many useful things in the first few rounds, and usually attacks the teammate a few times in the key early rounds, securing the win for the other team. These are no spoils games, so no real benefit from attacking the teammate, and it doesn't appear that they are doing it for something beneficial like holding a continent bonus. In some cases, spy simply deploys troops and ends the turn. But it's hard for me to be completely certain here. If spy is intentionally throwing the game, they are doing it in a relatively non-obvious way.
