If you signed up for the bottom one – the Hampton Inn / Facebook promotion – check your Hilton account. Both me and my wife got our 500 points yesterday, listed as ‘Hampton Facebook Great Stories’.
(It is worth noting that the rules for this one said ‘US residents only’ but, as I predicted, this was not really the case.)
The points for the first promo on that page, the Doubletree one, posted a couple of weeks ago. I’m not sure if either of these still work or not.
