[thelist] hiding email addresses

[graham.hays]

Apologies if this has been dealt with before.

Is there a good (simple) way of hiding email addresses from spammers?

I've been using the following approach but not sure if it works as
intended... it displays OK (forename.surname at domain) but will it fool
spammers? If not what does anyone recommend

XHTML:
<span class="hide">User: </span>forename.surname<span class="hide"><br
/>Domain: </span>@domain

CSS:
.hide {display: none;}


TIA
