Could you elaborate on this, Randall? I just followed the knowledgebase instructions...
I'm not Randall, and I don't play him on the internet (luckily for him) but you might want to check out NMSFormmail. It will obscure your address and is easy to implement.
However, even then I was would spam from the form...like it was cut and pasted into it and sometimes still do even though that form is no longer on our site. I guess that is because the address it was sent to didn't get kicked back
