One interesting approach I've seen is URI encoding e-mail addresses, as
web browsers will decode it, but it won't (unless they get smarter)
match the patterns for an e-mail address.
<A HREF="mailto:oneiros at dcr.net">oneiros at dcr.net</A>
won't match if it's encoded as:
(after all, if the spammers can send us crap that's URI encoded to make it
harder to track down, we might as well do the same to them)
