I noticed that under "new robocall recordings" the recordings are all from October 25, 2017. Not sure if this is a bug or you stopped updating them on that date or something.
But, the response to our sampling system has been really strong so we're expanding that to grab one recording per day per number. That way you can also go back in time and see the different scams that have been sent from the same number.
We're also building some deeper analytics so that you can see call volume by robocaller and graphs that show the changes over time.
