Can this be protected?

There's a nice little tool located at: http://hixus.com that does a good job
of obfuscating an email address. It generates javascript that can be
embedded in your web page. I have found that the scam artists seem to
actually read email addresses and write them down or otherwise add them to
their target lists but otherwise I don't seem to be getting much spam off my
web site. Recently though I've been getting email addresses to admin@ and
others prefixed to my domain name...
