Doesn't make any sense to me either. I did try some of the Share options and they all seemed to be dead ends. So did pasting the URL of the posting into Google Translate - I just got bounced into a Facebook login.

It would be handy to know what FB are actually doing, since I don't hit this problem with Google+, Gmail, Twitter, Tumblr, Mudcat, Reddit, Wordpress, XMB, YouTube, EBay, umpteen special-purpose forums or any newspaper sites.
