is it cheating to.....

announce a freestyle triples game as real time.
Then when the game starts each of the players from one team work together very efficiently, to take control of a continent and then the round ends they say that one of their players had to leave and that they only play as a team so they'll be back tomorrow?
They have a huge advantage because of this. There's no way that the three of us random guys that were playing against a bunch of people who know eachother would be able to coordinate a time to meet up? So essentially all three of them will be able to coordinate their attacks against us perfectly without any of us getting our armies for the next round.
We have no chance because of this. I've added the three players to my ignore list as I don't think that this is a legit way to play the game, but I wanted to see what others thought about it.
