I always wonder at these sort of tinfoil hat articles. It seems to me that someone who has the skills and access to the internet but does not leave much of a trace is a huge red flag for what ever the tinfoil hatter fears. A better strategy would be to boot in to your original MAC address then have a covert switch that randomizes it for doing things out of the ordinary, then returns it to normal once they are done. If you fear you are being tracked, it would be better to leave a completely normal, boring footprint that is easy to find. Normal boring Facebook page, tweets, etc. All the way down to a cache of vanilla porn on your hard drive with just a hint of kink for that ah ha moment. Then anything that goes beyond what you want that footprint to look like then moves to randomized MAC addresses, TOR networks and all the other tricks…
