Yes, I just found out yesterday that setting your referrer to facebook.com/l.php allows you to reliably bypass the paywall.
E.g. http://facebook.com/l.php?u=http://www.wsj.com/articles/poli...
E.g. http://facebook.com/l.php?u=http://www.wsj.com/articles/poli...
javascript:location.href='http://facebook.com/l.php?u='+encodeURIComponent(location.hr...
Make a bookmark with that, call it I'm from Facebook or something, and go to it when you hit a paywall.
