There is something slightly fishy about the report though, being that it says the 360 is banned based on MAC address. Those of us familiar with the OSI model and common network implementations will immediately know this is not true, because MAC addresses are part of the Ethernet protocol and live on Layer 2, and never get routed over the internet. In simple terms: your 360s MAC address is not remotely identifiable. An option could be that the Xbox Live login code sends the MAC address itself to the Live servers to be able to uniquely identify the 360, but that would be plain silly since MAC addresses are known not to be unique: they only need to be unique within their physical subnet. A far more obvious solution on Microsoft's part would be to use the console serial number for this, which is embedded in the system anyway and truly unique.
