Keifer Bly:
Will doing this make it more difficult for spammers to reach my address?
Yes. However, I think you should consider publishing your unobfuscated email address, for clarity and convenience to those who are legitimately trying to contact you.
I don't obfuscate my email address in the ContactInfo field, and I receive at most a few handfuls of spam messages per month. Most of these are caught by my email provider's spam filter, which I already have set to its least aggressive setting possible.
