I use my Yahoo address for the forums. Any Spam goes there, and most of it is automatically sent to a Bulk Mail folder and automatically deleted after a time.
I always elect to not receive the mail from the forums. Instead, I visit the page and read the messages there. Yes, you will have to deal with popups. I can't believe popups are effective, because everybody hates them. I would NEVER even read one, much less buy anything because of one
I had to reset my mail preferences with Yahoo only once, about six months ago. So far it had not changed again.
