Mark,
I doubt much if any of the spam you receive is a result of posting here. I do not use any "fillers" in the email address when I post here and get very little spam. It does not seem like email addresses are being harvested from the Chipboard. The little spam I do get is the result of another web site I visited and logged on. That was a mistake but I did not realize it until the spam started. Most of that has stopped now.
