I don't
see spam as a long term problem though.
Oh? I see it growing.
I do a lot of posting, usenet etc. and I always use my real name and my
email ID is my real name, and I never do anything to hide my email address.
Maybe 10% of my email is unwanted junk, split about half and half between
spam and web site junk where I failed to say no after visiting.
Spam is so far from my problem list it isn't even funny.
My sincere guess is that the solution to spam will be more of a PITA than spam.
