Do companies that do subscriptions know when multiple accounts are using the same card number? Just curious if they try to use something like that for fraud detection or anything. Then again, I don't think they'd care. Just take the monies and let the card people deal with it.
During the whole clamping down on password sharing era, I'd be very surprised if some folks haven't had to pay for multiple Netflix subscriptions (for summer houses, or their kids off at college, that sort of thing...)
