SatNOGS DB: Most Recent Observers


I would like to know if there is a way to correlate the data export to the observers when it is requested to download. It seems the .csv file does not include such information (or I was unable to find it).
The Most Recent Observers shows only the last five who uploaded data to DB and I could not find the entire list. Maybe it is private and must be hidden. In such case, forget my question please.
