Nope, I have not. Still, even at the risk of severely embarrassing myself, what's next to legislate? Am I being excessively worried here for no reason at all, hmmm?

Yes I do think you are being excessively anxious about it. Junk fax laws do the exact same thing with a different medium, and no one questions the sensibility, constitutionality, or utility of those laws. If you like the fact that you can hook up a fax machine without all your ink and paper wasted by people faxing you ads (you have recourse if they do), then you should like anti-spam legislation.

Spam is so pervasive that it renders email entirely unusable for a person whose address finds its way to spammers' lists. It's a quantifiable injury, not some imagined grievance.
