Email Protection with MooTools Javascript v2

Earlier this week I posted an article describing how you can protect your email links from spambots using MooTools. After some suggestions, I’ve made some improvements to my system.
The XHTML
<span rel="david|davidwalsh.name" class="email custom-class">Email me!</span>
I’ve switched to using a span tag instead of an anchor to prevent search engines from seeing dead links. We put the modified email address in the rel attribute.
The MooTools Javascript
window.addEvent('domready', function() {
$$('.email').each(function(el) {
var anchor = new Element('a', {
href: 'mailto:' + el.get('rel').replace('|','@'),
'class': el.get('class'),
'text': el.get('text')
}).replaces(el);
});
});
I create an anchor element and replace the span element that was originally there.
Thank you to everyone that shared their ideas — we came up with a better script!

This version is way cleaner, I assume I can change the pipe to any weirdo special character like �r5981327r0981; then do the replace?
Have you tested how effective is it against spam yet?
If it picks up any spam at all, I guess the next step would be to add in ROT13 to your approach.
Internet explorer 7 doesn’t like the “,” after ‘class’: el.get(‘class’)
That throws an error…
I tried to use this but my Browser does nothing if I click on the E-Mail me text.
@Birke: Works for me.
I had to add ‘text’: el.get(‘text’) to the new anchor element to be able to show the “Email Me” text.
@Wes: Good catch — updated that and compatibility with MooTools 1.3 (removed $each).
Thanks! The only thing i did different was to use title instead of rel. rel isn’t valid in a span.
