This my address gets a couple of hundred of spam messages per month
right to "Spam" filter. And, I think, I didn't expose the address
beyond the list. But, they may build addresses, not necessarily they
have to harvest them. The address kind of boston@gmail.com would be
receiving tons of spam without participating anywhere.
