Many users and forum programs in attempt to make automatic e-mail address harvesting harder modify them replacing @ character with "at" and . character with "dot".

So that

team@example.com

becomes

team at example dot com

Is there any special term for this practice?

Wow. Using other people's email address in a question about munging... (Changed to example.com as per RFC 2606, hoping bots don't get into the revisions.) – Arjan Oct 13 '09 at 13:38
    
Is this really such a problem? The original address has been on each page of this site for ages. That's specifically why I chose it - it's already here. – sharptooth Oct 14 '09 at 12:15

As well as obfuscation, it is often referred to less formally as "munging".

Obfuscation?

Obfuscation is the concealment of intended meaning in communication, making communication confusing, intentionally ambiguous, and more difficult to interpret.

Edit: Of course, in this case we're talking about making the communication confusing for spambots, and not for humans.

Well it can be a little confusing for humans too. It's easier to skim some text looking for "x@y" than "x at y". – DisgruntledGoat Aug 11 '09 at 14:03

Anti-Spambot Encoding ?

Of course the opposite then would be 'Anti-spambot Decoding' ;-)

But on a more serious note: I think @David is right with his 'munging'.
Even more specifically: Address munging would be the right term (according to Wikipedia).

I'd consider it a form of CAPTCHA. The Turing test being not so much the transformation "at"==@ and "dot"=dot, but finding and recognizing such disguised email addresses in a text that contains lots of other "at"s and perhaps even a few "dot"s.
