Yeah, I agree in this case diversity and invention is the way to go  
it's just that millions of people have thought: "I'll hide my address  
like this" and bingo made the situation worse.  I think a similar  
automated solution is built in to google pages and hypermail/ 
pipermail archives isn't it?

It sticks in my mind for some reason that when email obfuscating  
first started some guy used to obfuscate his address like this:  
fredpants at pantssmith.com (remove pants to send email).  It's amazing  
that this is still not a bad method.


A quick search and scrape script would get you most of the TLDs.

Adjust the search string like this: "*at*dot*com"

and you get a lot more (79,000,000), ones like:
fredsmith/at\fredsmith/dot\com

The string : "*at*gov*dot*au" gets about 36500 hits.

The string "at*dot*au" gets 19,400,000 hits.
