According to how this works, all credit card debt is bad. The understanding used to be that carrying debt and not paying off the balance is bad. Now it's how much you spend. I pay my card off in full every month. If I spend more than 3500 of the 7000 max, my credit score dips 50 points and then the months where my spending is 1500 or less, I get it back. You would think they would want you to spend as they make roughly 2 % on each purchase.
