No, there's an analogue of the CVV2, the CVV1, which is only present on the magnetic stripe. The information you'd get from an online transaction is not enough to print a working magstripe.

There are still offline processors that don't read magstripe and just take a copy of the card and a signature.

Yep, ever have a merchant enter your CC number on the keypad IRL? That's what's happening. The fees for these types of transactions are typically higher as your processor is assuming more risk, so they prefer to only do them when they need to. See https://www.mastercard.us/content/dam/mccom/en-us/documents/... if you're really curious about how this stuff works in the MasterCard case. Visa is similar AFAIK.

Not a repeatable form of fraud. You won't be able to make money abusing offline processing.

Why not just buy magnetic stripe dumps for a couple of $ each online? Significantly better risk/reward ratio.
