Null receive reports

I've been monitoring 50 MHz 24/7, but haven't received any stations for a couple of days. This is usual for 50 MHz.
However, I see that I am still listed in the "Activity" area as being an active receive station on 50 MHz, which is true.
Does WSJT-X send a "null" report over the Internet to wsprnet regularly, just to indicate that the station is still listening on the band, albeit unsuccessfully?
Does this happen every 2 minutes? Every 10 minutes?

Just curious. Thanks.
