Out of curiosity, I was looking through PayPal's and eBay's websites. I just wonder if anyone has had the nerve to post a fake auction for $5,000 that offers Anything Points (which can be converted into miles using Points.com), and "purchase it" using another eBay/PayPal Premier account and pay with it with a credit card (earn more miles for that). Would it even be worth it to do part or all of this?

How soon would they catch you and would they close your accounts?

I've recently took a look at the PayPal website more closely. PayPal certainly now looks like a bank. One can keep money in PayPal in five different currencies, and use the service to transfer money between banks, and it is even possible to transfer money between banks in different countries, although you might need two different personal PayPal accounts to do it, with the other needing to be registered to a "user" in the other country. It looks like the service could be used for money laundering.

But my interest here is could it be used for earning miles, or would I just end up being thrown off their service and/or eBay?
