Regarding spoofing your url..all you gotta do is change some basic front end shit and make your url look like any damn site lol
I use the Facebook feed dialog..
Here's the URL template, which you can use. Just save it in a notepad and update manually lol. Post a dummy page, then share the facebook post URL:
Code:
https://www.facebook.com/dialog/feed?app_id=966242223397117&link=http://www.google.com&picture=http://cdns.yournewswire.com/wp-content/uploads/2015/07/aliens-bear-sized-620x264.jpg&name=Aliens invade the White House & Abduct Donald Trumps Wife for Mating Ritual&caption=I LOVE PORNHUB &description=Will your wife be next? Click here to find out how to save her.&redirect_uri=http://www.facebook.com/&display=popup
app_id= YOUR APP ID
link=YOUR DESTINATION URL
picture=IMAGE URL
name=TITLE
caption=CNN.COM or anything you want lol
description=DESCRIPTION
redirect_uri=After sharing people get redirected here. It needs to be a domain you choose in your fb app settings. I am using bit.ly with a custom domain, but you can just use any of your domains and 301 redirect to another URL.
Basically every parameter can be updated here, and also update the APP id so that when people share, you can further redirect them to another page or else they will be redirected to the facebook homepage..
