The machine's MAC address does not leave your local network and therefore is not available to web or other servers. There is no possible way for a site to track that information, unless they ilegally have access to your computer.

In addition to this, the MAC address can be easily changed as many times you want and using as many combinations you want.

Try to learn a bit, before you write non-sense next time.
