Just got a robocall that said "is sending you a hey cosmo blast, press 1 to hear the message". That’s right, no indication of who, it just started with the word "is".
For obvious reasons, I didn’t push 1.
Google searches suggest that the company responsible is http://www.heycosmo.com/
On the off chance someone I know tried to use that site to send me a message: it failed.
My money’s on someone trying to use it to spam, though.
