She wasn't saying the actions are muddled, she was saying spotting them is muddled. As you move up the list of nearly 5 million players, moving from those that have nothing to those that have everything, there is no clear line whereby everyone below it is legit and everyone above it is a cheater. And if you can't catch and eliminate them all, how do you pick and choose?
I don't think that's true. My wife's account and mine are both fed by the same Credit Card (not that we use it that much) but we're charged by iTunes. They then pass the money on to BFS, minus they're %, but I don't think there's any correlation between the money BFS receive and who has what in the game. I don't see how they can police 5 million players to find out who's cheating and who's not.
The good news about all this is that none of it really matters. Who cares what people have done what to achieve what? I spend a great deal of my parenting life instilling in my kids that judging others is a waste of time and comparing yourself, what you have and what you've achieved against others is not a path that will lead to happiness. Other people are free to do what they want. Your own race is long enough, and is only against yourself.
