No, the ampersands have to stay intact.  Double-converting will end up just 
displaying the codes instead of the letters.

Unfortunately, this will eventually lose its usefulness as scrapers (both 
for spam and viruses) become more intelligent - and even now it cannot 
guard against point-and-click one-at-a-time spammers.  Last week I received 
a Nigerian scam variant sent to two addresses that are only posted in two 
places, and only with this type of obfuscation.  (To add insult to injury, 
they were our abuse contact and our false positive reporting address!)
