Comment (by nacin):

 A custom field that starts with an underscore does not pass this check. It
 is considered "protected" and cannot be modified through any UI, which
 includes a generic XML-RPC method.

 If you wish to whitelist a custom field, you can use register_meta(). This
 takes a meta type (i.e. "post"), the meta key, a function to sanitize the
 value on save (similar to the sanitization callback for
 register_setting()) and an authorization callback to determine whether a
 user can edit_post_meta, add_post_meta, or delete_post_meta.
