Update.
On XP, I found you can spoof your mac# by installing a VPN, then going into the properties of your network bridge, and just changing the mac numbers yourself. However, when I logged out of my VPN to do some file transfers to our server at wearebty.org, I made the mistake of leaving one tab logged into facebook, and within a minute of switching the VPN off, I lost another facebook account.
Logging out of the VPN didn't change my mac# back, so I've come to the conclusion that a VPN is the way to go. Also, I found out since, that facebook uses session cookies to throw security verification blocks on flagged accounts.
And that if you use a Chromium browser like Chrome, or Torch, you can set up different user accounts within the browser, each with it's own cache of session cookies. So using a VPN, and a Torch browser, I've managed to keep an unverified facebook sock account for nearly a week. (The last 17 accounts I've made, lasted 2 days at the most)
Not bad, seeing as I only learned how to set up a VPN about 10 days ago, and only ever heard of mac#s for the first time about three weeks ago. I'm currently learning html too, from some top coders, so yay, go me!
