There are AA million milers who were heavily into the AA Citi card churning game. While some of those AA million milers should be happy that they got the MM status they did years ago, I have to assume some habits die hard and that some of them remained active in the card churning game in major ways or dipped their toes into repeating old habits of sorts even years after it would no longer be about MM status.
