I've somewhat helped this problem by masking the email addresses using html entities
for the bits. Basically, a script runs down the length of the email link and converts
it to the format &#(number);&#(number); etc, where the "number" is the ascii value for
that character. Apparently, you could replace just the ampersand with this pattern too.
It cut down on a lot of that farming you're describing. Browsers render the email
address normally.
I have one example of the function in vbasic/asp and one in php if you'd like to see a
closer look (they're basically the same thing). If you're coding HTML pages, you can
just convert it before you type it (rather than using a function).
Here's where I acquired the concept:http://www.cdt.org/speech/spam/030319spamreport.shtml
