Got a survey robot call.  Said "Can you hear me" twice.
I was silent -- the robot hung up after 22 seconds.

I also got a robo call from these creeps.  I think this came about when I replied to a paid focus group on craigslist.  However be careful should you reply to any craigslist ad.  The ad I thought was legit was posted in the early AM so check the posting times for ads - it has been my experience anything posted on craigslist in the wee hours is spam or an offshore scam

Got a call from this number this morning 4/26/16, I didn't pick up since I didn't recognize the number. They did not leave a message. Scam for sure!

Called on 4-26-2016, left no voice mail.

I got a call from this number, but I haven't responded to any craigslist ad.  So they probably got our numbers through another source...
