 * Hi all,
 * Is there any obvious way of hiding email addresses behind a captcha?

 * It would need to be JavaScript or jQuery of some sort. I’m not sure exactly how
   your script would interface with reCAPTCHA, but it would somehow detect a successful
   input and then display the email. How securely you want to obscure the email 
   determines how the email is stored in script to begin with. If this is to merely
   hide addresses from automatic email scrapers, a simple assembly of parts would
   be adequate. Some sort of simple cipher will stop all bots and most inquisitive
   humans. For maximum security, get the address from the server via Ajax. Anything
   sent with the original page prior to successful reCAPTCHA response can be eventually
   decoded by anyone determined enough.
 * If your intent is to merely stop email scrapers, reCAPTCHA is overkill. AFAIK
   scrapers do not interpret JavaScript, so running a replacement script on page
   load should be adequate. Or present the email as an image. Bots do not run OCR
   either.
