The current system of entering an email link -- or even just typing an email address in plain text -- does nothing to thwart nefarious spiders from harvesting them. I have utilized various methods on my own in the past (as well as currently), but perhaps a built-in system to obfuscate an email address could be implemented in v8?

Right now, I use the active text to replace @ with
HTML
<span class='email'>snugglebunny</span>&ordf;<sup>t</sup><span class='email'>owns</span>
where the email class is display:none;
