I've generally found that encoding the address as HTML character
entities works fine. I've had a bait address on my web page for quite
some time, and it's never received any spam. It's readable to text
browsers, it doesn't affect readability with unexpected font sizes, it
takes little computation, and it's trivial to write.

My address would become:
&#100;&#103;&#99;&#64;&#117;&#99;&#104;&#105;&#99;&#97;&#103;&#111;&#46;&#101;&#100;&#117;

I've long favored this approach where display of mail addresses offends
people.
