The answer to spam (as long as spam exists) is not to run from it, but to put it in its place. Email addresses are nearly useless if they're not public. But you need a good spam filter. This is one of the reasons why I'm still using a Yahoo email address after well over a decade. Its spam filtering is quite good. I have no qualms about using my Yahoo address for all my ordinary public needs. (yes, I also have an account on a different email server which I only give to my most trusted contacts.) It is quite liberating to not have to worry about whose hands your email address will fall into.
