I would be surprised if harvesters don't catch this now (or soon). Even mail 
clients such as kmail do it (if you copy "foo (at) bar.com" to clipboard, and 
paste it into the To: field, then " (at) " will be replaced by "@"). This is 
a sign that the (at) trick is so commonly used that it definitely would be 
"worth" implementing it in harvesters.

Anyway, I prefer a different approach for my homepage, using a hand-drawn 
image. That should be safe.
