Spammers usually 'spoof' the address from which the email is sent. You'll be bombarding, at best, a non-existent address (and you'll receive "cannot deliver" messages for each attempt). At worst, you'll be inadvertently spamming some unsuspecting innocent who just happens to share the email address that the spammer has used.
