No that's not the reason why it gets you banned. The reason why it gets you banned is when hundreds of people are using the same card. Even 2 people using the same card from different locations at the same time would be considered fraudulent. The "bin" I posted was meant as an example. Not the bin you should use. If you use a bin and generated card that isn't commonly used, they won't be able to know otherwise whether it's real or fake unless you're stupid and try to make a payment.
