Feedback

They could just take their laptop to Starbucks and create a new account and their IP address would be different. Or, they could even bid from their cell phone.

or they can just swap out their existing network card for a $9 network card in their computer, or they can bind (or unbind) their computer's MAC ID to/from their router.

It's in the terms of service in bold red letters. Don't pay, manipulate the bids, etc. and your IP address is permanently blocked.

I think you missed my point, Travis.  I am saying that since there is already a remedy in place for anyone who doesn't pay, there really isn't a point for feedback.  Just doesn't seem like an avenue you need to pursue at this point.
