An anonymous reader writes "One of Australia's gaming networks, GamesArena has recently imposed a third party program required to access their gaming servers. One of it's features is that it records your NIC's MAC address to identify your computer, and subsequently in future, ban you if you cheat/break the rules etc. The response from players is mixed. It is not open source software, nor is it optional to install. "Install it or find another server to play on". Question remains, is it going too far?" Definitely not- unfortunately it won't work since MACs are changable.
