This probably runs afoul of the
Speculative Booking rules. But, like you said, you are going to be banned anyway. You will likely get caught before that, especially if you book them all while logged in.
You may not use Southwest's sites to make any speculative, fraudulent, or false reservation or any reservation in anticipation of demand. If you have made multiple reservations to one or more destinations on or about the same date, Southwest reserves the right to cancel all such reservations without notice.
