Did they cheat during these games? No? Oh well.. that says it all. And it doesn't matter how much you think and change about it, there will be teams that profit from other teams cheating whatever ruling you decide to have. If a team break rules outside the actual gameplay you always have to consider how many games they have played if they are disqualified. And if that goes above 66 percent there's only one rule to apply if you want to refer to fair. Look it up if you think otherwise. It's another story if they cheated during the games they already finished.
