Who said anything about sending MAC addresses to the internet? Every time you guys respond to me, you put words in my mouth. It's dirty pool to argue with my point by rephrasing it in a way suitable to you.
Anyway, why are you fixating on the MAC address thing? Who cares about it, it's just one part of my suggestion. My point, which I will reiterate, is that dodging from one piece of hardware to another and using public, anonymous access points in nearby towns will make it virtually impossible for anyone to definitively tie you to anything you say on the internet. It's not just the MAC address, it's making sure nothing recovered from the disk can trip you up, making sure they can't tie your hardware and OS to the comment somehow, etc, etc.
It wouldn't be difficult for a corporation to have someone figure out where you're posting from, then try to watch and log the traffic at that access point. Most internet forums don't use SSL. This one doesn't. If they want to log your MAC address while they're at it, it shouldn't be too hard. You're not using your imagination; you rely on your test prep book too much, CCNE-guy. You have to think of worst case scenarios, and see how they'd try to get you if they were annoyed enough to put some effort into it.
It doesn't matter what MOST do. It matters what some MIGHT do.
I like the idea suggested by another poster: rip the hard disk out, use a dongle and a live CD, and use a ramdisk as a temp disk. I can't think of anything wrong with that approach.
Guys like you are a trip. SO confident. SO sure of yourselves.
