I wouldn't worry so much about spam from your e-mail address appearing here. E-mail spam is a declining industry and it doesn't appear that there's much continuing incentive to scrape websites for e-mails to spam.
Good to hear. That would be an interesting experiment too -- add a very unique email address and see if or when spam appears.
I've had an e-mail address on my writing website for about a decade now. I get very little spam sent to it. The bulk of the spam I receive is to my oldest e-mail address which I had once upon a time used to post on usenet.
