safe mailto

[eluser]vertmonkee[/eluser]
I've just been looking at the safe_mailto function which outputs the address through javascript to hide it from spam bots.

If the user does not have javascript enabled no email address is displayed. So I've put the plain text version of the email after in a noscript tag like so

Code:

Email: &lt;?php echo safe_mailto('[email protected]', '[email protected]'); ?&gt;<noscript>'[email protected]'</noscript>

My question is, by doing this do will spam bots stil pick up on the email address or do they tend to just look for a <a href="mailto"> link?

I know you can never completley protect against spam, just wondering if it worth me bothering with this technique.

Thanks
