Incredibly, it's still very effective.  Back when I kept a personal
site with actual content, I kept an entity-encoded mailto: link to
asswipe at quillio.com on all pages.  For maybe eight years (up until
about four years ago), that alias never received a message.  I still
use entity-encoding mailtos on public sites and don't have the
impression that they're scraped.

I think the harvesters are all about low-hanging fruit, and decoding
is still more expensive than it's worth.  Might change some day, but
doesn't seem to have -- yet.
