There is a third option: you have no clue what you're talking about and you're just trying to waffle your way through it.

The scam is not just someone hypothetically defaulting on future obligations, which wouldn't be specific to SES account sales. The scam is also the "method" those account sellers use to obtain the accounts (hacked/fake payments/etc) and to move them from SES sandbox to production mode to get the 50k limit. Because sure as shit they are not using their own personal details, they have to lie to support to get the limits raised, and they can't create those accounts anonymously, otherwise it wouldn't cost $200+.

So yes, they're scamming Amazon.
