Are you sick of scammers scraping your email address of your website and then selling it to spammers.  You could do what a lot of people do and obfuscate it through the use of a javascript.  Then again, Google search guru Matt Cutts says, you might want to think of another way.

If you aren’t sure what I’m talking about I’ll try to explain it very simply.  Through the use of a very easy to use java script, you can make your email address invisible to the robots that scrape your site looking for email addresses.  Thus, people can still email you from your website, but the bad guys can’t steal your address.

Now Google comes along and says “not so fast there Mr. Security.”  Google is getting to the point where their robots are starting to have the ability to read java.  That means your email address could very easily wind up in Google search results.

Check out this video from Matt and see what I mean.
