I have not been able to get points for my Foursquare check ins but my wife gets them with her Facebook check ins.

Did you use 4SQ or facebook?

I had been using 4SQ and have received nothing since the 12th.

Out of interest I just linked to my FB account via Switchfly and it shows the full history from Topguest with the latest being late August (even though I've done 4SQ checkins since). So looks like that's the way to go forward.

Scrap that. Upon linking, it then shows you Foursquare (which is obviously already linked) as an option as well. Ho hum.

I have only used 4SQ.

Received my last 50 points on 9/12. None since then. I assume the ride is over.

I've still been receiving points for DoubleTree 4SQ Checkins

No 4SQ points for me either since early September. The deal still shows as being at the hotel and active on 4SQ, but it doesn't work. I didn't crush it, but I did at least get 10k over the past year or so out of the deal... including multiple check-ins as I drive around town, not all the same hotel.

Ditto, no credit here in a few months now. It's interesting to see that on my Foursquare feed hardly anyone is using it (4SQ) anymore.......

I just received 50 points for a doubletree checkin at the beginning of November. There are one Doubletrees where I live, so it is only when I travel. However, it is nice to be able to keep the Hilton points alive in this way.

As reported, I received points at the beginning of November. I was at a Doubletree a couple of weeks ago and checked in, but no points have posted. I just checked their website and the following was posted:

Yup, they're kaput. I think it was ~ 10/1 when they went belly-up.

It was a good run while it lasted...

It seems like it's resurrected in some way or another.

I'd checked in to a Doubletree IIRC in early January 2014 via Foursquare and got nothing. Then, I found the posts here about what happened to Topguest.

Today, I did the same thing at another Doubletree (the one I normally use) and shortly after received an email w/the subject "You just received 50 Hilton HHonors points from DoubleTree Social Rewards". Hmm...

Looking at my emails, the last one I got from sender Topguest was from 6/2013 w/the subject "You just received 50 Hilton HHonors points from Topguest".

The ones I received today, 11/2013 and 10/2013 were from DoubleTree Social Rewards w/the subject "You just received 50 Hilton HHonors points from DoubleTree Social Rewards".

In looking at my Hhonors account, the last time I received a "DOUBLETREE TOP GUEST CHECK IN BONUS" of 50 points was on 1/29/14. Not sure if that the check in was the one from early Jan 2014 w/a huge delay or some other one.

I also received some late last year on these dates:
03 Nov 2013
14 Oct 2013

Seems still works for DoubleTrees only.

Did 3 check-ins at DT Kuala Lumpur on 3 consecutive days from 17th Jan 2014, all were posted within 2 weeks.

Checked in to a Doubletree earlier today, and just received email that I earned points. Now to see if they actually post...
