Comment (by ayeshrajans):

 Hi @ryanrolds. I'm not a core maintainer and I hope one of them will reply
 to this ticket soon. I also think an appropriate error response code makes
 sense.

 I went ahead and made some changes so that invalid/forged `admin-ajax.php`
 requests die with a `400` error code. It will still print `0` to the
 screen (for compatibility).

 Attaching patch. Link to tests: https://travis-ci.org/Ayesh/wordpress-
