tbh I thought it would be a problem when I set up - <trillions of combinations of letters and numbers>@mydomainname.com - thats going to be a lot of email. It turns out that nobody knew I existed so didnt get all that much spam for years. Back then slapping your email on your site / forum footer etc was the way to get on the spam mailing lists.

Then along came web facing databases with no auth defaults, and you can have a billion active, in use email addresses with a living breathing human at the other end (and their username, password and dob) for free.
