Tracking by MAC addresses
Tracking by MAC addresses wouldn't be very reliable either.
Tools that spoof the MAC address are a dime-a-dozen and it doesn't take a rocket scientist to figure out how to use one.
Granted, there will always be a few that won't know how to do this but in the age of Google all you have to do is search a few keywords and you are presented with all kinds of information regarding your topic of search.
[QUOTE=NC Transplant]Tracking by IP probably wouldn't work if you used a public internet access like Starbucks or Barnes & Noble as your IP address comes from your internet provider. Every computer has a unique MAC address, but I would think that would be harder to track?[/QUOTE]
