I think it's just a way to document.write his email address, so no bot/crawler can directly see it. Edit: It evaluate to `document.write('HIS_EMAIL at gmail')`

  If the browser can do it what's stoping a headless browser bot from evaluating it all the same? Is it just to lower the attack surface?

    Evaluating all javascript to see if it eventually writes an email address is not a good idea. In fact doing so probably violates the halting problem somehow.
