Works for me.. have you tried it in incognito mode?
I think they're using some kind of heuristic approach to identify people who use the google approach regularly and put a stop to it. I know sometimes when I click on a Journal article it will let me read it, sometimes it won't. It's a tricky tactic, I'd just totally ignore Journal links otherwise. But this way they get to bug me semi-regularly instead of not at all.
No, it's referer and cookie based.
I just tried it and it seemed to work for me.
which i find pretty sad. that hurts both the wsj, who would rather be paid for your reading their content, and the creative commons alternatives for your time and attention, because people here are now reading and discussing pirated wsj content rather than genuinely free-as-in-everything writing.
They use cookies now too, try Incognito mode (or whatever is similar in your preferred browser).
