I was very unpleasantly surprised when I hovered my mouses over the email (envelope) icon to the left of one of my posts to see my email address in the "send mail to" at the bottom of the screen.  I went to my profile and indeed the subject checkbox was checked as I was sure I would have left it.  So I changed my email address to a non-existent one.

I started receiving spam not caught by Google's filter a few days ago at my real address.  I'm not sure this Forum is to blame, but now I have my suspicions.

Yeah only you will see that, doesn't work for me.

Yes.
