How to exclude tagged posts from Facebook Graph API response

I'm using v 2.8 of the Facebook Graph API, and am trying to get a list of all posts from a Facebook page, but excluding all mentions of the page from random public posts. I have thousands of Facebook pages and millions of mentions, so it's important to drop the tagged posts if possible.

I've tried the following:

{page-id}/feed -> Provides All Posts Where Page is Tagged, Posts by Admin, and Posts by Users on Page

{page-id}/promotable_posts -> Returns All the Dark Posts (but no posts from users on page)

/{page-id}/tagged -> shows all public posts in which the page has been tagged (opposite of what I want)

Summary: Is there any way to get all posts by users (not by a Page Admin) on a page itself (not just public mentions of that page).
