Won't UDEMY find out about this and shut down your account? Sharing this is against their terms of service:

Because of this big risk, I would say that if I bought from you, we must use an escrow where the funds will only get released upon receipt of all the courses as promised. If any less, the escrow should only release the payment of those courses that are received and then refund the rest back to the buyer
