Technological progress is like an axe in the hands of a pathological criminal.
— Albert Einstein
With new technology, comes new concerns. In the case of electronic mail, it is that of spam. At least when we get junk mail at home, we can quickly sort through it and drop it into the recycle bin. The fact that you have to pay someone to print and deliver the flyers does serve to deter companies from filling up everyone’s mailbox with non-addressed mail. Spam, on the other hand, can be sent for almost free. I guess they must make some sales out of it, or you would think that they would have given up on the tactics long ago. But where do they get email addresses to spam? Unlike delivering flyers, where you can just walk down the street, you have to actually know someone’s email address.
