I stumbled upon this campaign on Facebook (possibly by SW airlines.)<p>https://www.inbizi.info/southwest/?tr#
(NOTE: Don't give access to this app. Its spams on your wall / photos)<p>Refresh this page, everytime it shows a 'Login to Facebook' via Sponsor (Yelp, FourSquare, AirBnB and so on).<p>My question - does Facebook allows this? Is it done with permission (or through sponsorship of FourSquare / AirBnB / Yelp and others?)
