That's called zoemail. It was patented so long ago that the patent expired
a year ago. See patent 6,643,686.

It's also a Well Known Bad Idea since it just replaces the intractable
spam problem with the equally intractable introduction problem.

This isn't alt.spam.argue.argue.argue, so I'll just say that I've
lived with the technique by overloading the email address with the
token. And it is much more effective than you might expect.

I've probably been using tagged addresses as long as anyone. They are
handy for telling who leaks their addresses, but they are far from a
FUSSP.
