Advertised as "The Powerful WordPress Plug-in that Allows You to Convert Any Keyword in Your WordPress Blog to an Affiliate Link with Only a Single Mouse Click!"
I'm thinking "yes it's a scam" because
(1) the logo they use isn't the WP logo we know and love
(1) it's not free
(2) I've never seen other plugins advertised on Facebook by a 3rd-party
(3) they're running a sale which conveniently ends in 24 hrs
