Other than the operational issues, like not have a good way to contact amazon, this reminds me of a 900-number system we ran at MCI.

When you registered for a 900-number, you had to submit a script along with it. MCI would try to limit the possibility that you'd use it for some nefarious purpose, all CYA. They had a team (probably one person) that audited the numbers periodically. That didn't stop people re-using the numbers for bogus financial services and adult things.

We went through the same thing a couple years ago with an SMS short code. Had to submit a script (despite it being dynamically driven), set a max number of messages per month (despite it being user-initiated), etc.

The real kicker is we once got a massive nastygram from Verizon threatening us with shutdown - they claimed we were sending porn spam messages via the number. After quite some time auditing our entire stack we got a "our bad, one of our techs had malware on their Android phone" email.
