Re: Email spam bots - display name vs. actual email address
If you can read the source and at least deduce what is most likely an e-mail address, so can a bot.
Therefore, if you want to provide the user with on-site contact, use a secure form; if you want to provide for their e-mailing you, display the address as an image.
Be aware, though, that even images are not guaranteed to be unreadable by bots. By employing OCR, and building a database of observed CAPTCHA images and the corresponding proper characters, there have been bots available for some time now that serve as effective CAPTCHA decoders.
