I get a lot of spam. My Google Mail account has a folder just for spam and it stays at around twenty thousand pieces all the time.
Gmail automatically deletes items in the spam folder older than thirty days, so that means I get around twenty thousand individual pieces of spam every month.
Can you imagine? If all this junk mail were physical rather than virtual, my postman would have to deliver the mail with a fork lift.
Granted, my email address is plastered all over my website, but that's still a huge number.
