The Facepile Social Plugin only shows friends to friends...
Why is nothing displaying?
The plugin only displays friends photos. If the user does not have friends who have liked your page or have connected to your site, no faces will be shown.
I removed all "Like" buttons, links to FB and other such promotions of Facebook from all sites some time ago -- for exactly the reasons you've (now) figured out.
The only way I've found to use FB is to post brief teasers with links to my sites -- but the conversion rate is abysmal, and IMO -- not worth the time.
