The two players tqt and hhxyz at the very least agreed to collude before the game in a FFA, which annoys me by itself. I reported them as possible alts of the same person because of the similar profiles and similar way they played and, obviously, the fact that they "colluded".
A couple of the turns I saw them do something that didn't really make sense to me if they were actually the same person. In Turn 2 tqt moved two armies from Istria to Dalmatia, and in Turn 14, both of them attacked Trabzon. But given the way he/they played, as well as their win rates, maybe the person just didn't know what they were doing.
Even if they were two people, it seems like a shitty, dishonest way to play, joining a Free For All with a friend and not attacking each other as opposed to making an alliance during the game.
