This must be an issue from time immemorial - well as far back as the
original web pages of the last century.

But what are the best ways to stop email addresses being harvested -
and therefore sold for spamming - from: 1/ the text of a web page, and
2/ the source HTML.

This was 'solved' in a rather inelegant fashion as per this page:

http://home.clear.net.nz/pages/geoff.rodliffe - then click on 'Author'

That is with the use of " AT " in place of the usual "@"

But this is a fudge.

I found one web site with another idea at:

http://www.redalkemi.com/contactus.php

Here they have replaced the page text with a small graphic displaying
the email address. The link behind this is to the actual email
address. But this would not stop the harvesting of the addresses from
the HTML source.

So does anyone have any other solutions please?

Best method: Don't display the email address in the page - use a contact form in the site, with server side anti-spam measures (Captcha, recaptcha or other methods) and the sendto address added by the server side script - reqiores asp, asp.NET, PHP etc.

Alternative: Use javascript to write the email address to the page:

<script type="text/javascript">
var user = "someuser";
var domain = "example";
document.write("<p>Email: <a href=\"mailto:" + user + chr(64) + domain + ".com" + "</p>")
</script>

Most webots have javascript disabled, so they will see nothing - caveat: users with javascript disabled will also not see an email address.

Excellent - now is there a way of detecting whether a user has
Javascript enabled (hmm - but I'd also need to detect the browser
being used I guess!!). Then if so I could code something like:

If Javascript enabled then show this, otherwise then show that - kind
of thing.
