Errata Security: I conceal my identity the same way Aaron was indicted for
Jared Sperli stashed this in security
Besides taking the "civil liberty" angle, I'm trying to get to the "witchcraft" angle. As Arthur C Clarke puts it, "Any sufficiently advanced technology is indistinguishable from magic". Here is my corollary: "Any sufficiently technical expert is indistinguishable from a witch". People fear magic they don't understand, and distrust those who wield that magic. Things that seem reasonable to technical geeks seem illegal to the non-technical. The non-technical think they understand MAC addresses and address blocking, but they don't. Thus, Aaron's indictment might seem a fair interpretation of the law, but it's a wholly unfair interpretation of technology.
So, anyway, at the bottom of this post is the magic incantation you need to cast over your MacBook in order to randomize your MAC address. I recommend against you using it, though, because this may cause a bunch of villagers to come after you with torches and pitchforks.
