Subscription to spam National Geographic used to be a very respected journal. Now, they teamed up with Lindblad Expeditions. Once you subscribe to National Geographic, they sell your address to Lindblad Expeditions without asking for your permission, and you start getting catalogues of offensively expensive travel offers, tens of thousands of dollars per trip, from Lindblad Expeditions, and it is impossible to stop.
