Hide Email from Spambots but not from users

i always love to click the mail button instead of typing and matching email from the image.
Spammers have made our lives miserable

using this little piece of javascript can give you both, a text email link and no spam

most of search engines + spam bots don’t check the script tag, but even if they check that who is gonna extract email from the script

1. <script language=javascript>
2. <!--
3. var linktext = "Contact";
4. var username = "Admin";
5. var domain = "website.com";
6. document.write("<a href=" + "ma" + "il" + "to" + ":" + username + "@" + domain + ">" + linktext + "</a>");
7. //-->
8. </script>
9. <noscript>
10. <!-- No Script for searh engines and spam bots -->
11. <img src="http://mydomain.com/myemail.jpg" alt="Im sorry but youll have to type it manually" />
12. </noscript>
13. Download this code: nospam.txt

I see dead Spammers hehehe.
