I've got the wpForo Embeds installed and made a topic to test various link embeds. Most of them work but the most likely one to get used is Facebook and it doesn't work. When I put a Facebook link to any public post it displays:
This Facebook post is no longer available. It may have been removed or the privacy settings of the post may have changed.
