No.

It is supposed to protect from spam bot. It doesn’t.

Yes I understand that. You’re right, no doubt. ;)
(it would be better if there was a random coding as here
and the only 100% safe way is a mail form)

It was just about heikki74’s message I hadn’t understood…

This is also intersting (sorry it’s in French) : you can see exactly the e-mail adresses a bot can find in one page. Txp e-mail coding is considered as “trivial” (and easily decoded ofc course).

So now… Who will make a plugin out of that ? ;-)

Ok.. I’m ending my experiment now. Too much spam is getting through when spam-assasin is turned off.
I also found a site about spam harvesters: Project Honey Pot.

My results: (duplicates are included)
Plain email link: 18
Txp style encoded link: 6
Simple javascript: 0

See earlier messages for explanation.

I’m not allowed to use third party e-mail forms on my host, so at the moment I’m encoding my addresses using mixed encoding methods. Just knocked up a plugin: dtj_obfuscated_email

No real documentation as yet, but simple to use. Takes an email attribute (the address to be encoded) and an encoding mode (case insensitive).

Mode Attribute:
basic – a really basic e-mail encoding
iso – encode with your usual ISO character entities
hex – encode with Hex character entities
mixed (default) – randomly encode using a mix of ISO and Hex encoding methods

Syntax:
< txp:dtj_obfuscated_email email=“encoded address” / >

Example (pretty much as textpattern’s own email tag):
< txp:dtj_obfuscated_email email=“noone@example.tld” mode=“iso” / >

If anyone has any feedback on it, I’d be interested to know.

Edit: Updated with new URL and a bit of documentation.

I was reading about <a href=“http://www.wait-till-i.com/index.php?p=6”>this</a> php method. Thought it might be of interest

Thanks… nice idea, but share the concerns in the comments. Referrer checking is unreliable. I know of another method which involves using a form submit button, which can occasionally be styled to look nice.

As an example, check out the comments from a page from GAWDS.org

It’s a bit of an ugly hack, but as far as I know, it works pretty well.

Give the Enkoder a try.

Of course, the problem with a JavaScript solution like that, you don’t have a back-up for when JavaScript is not available.
