Well, if I had done that, my own email account would have been declared spam. Spam catching software usually filters out the kind of stuff I'd been receiving. If I had forwarded it, I would have been identified automatically as a spammer.
Much to my annoyance, I felt obliged to remove the Contact form on my website and substitute an encrypted email link.
Guess what, since I did that, the spam from email@example.com has petered out. I STILL am not sure whether it was the email address or the script that was vulnerable.
