All that is available is a username and a location accurate to within 10km.
Yes, there isn't too much personal information there but the other information is very useful when helping other forum members.
For example i can see that jonhawkes2030 has several feeders and one of them has the highest number of reported positions in the area (congratulations, well done).
The coverage distribution shows large numbers of positions nearby in the NW direction. Meaning that is likely where the nearest airport is.
Looking at the map on the stats page confirms this, as jonhawkes2030 is shown in the Bay Ridge area to the SE of Newark Liberty International Airport.
All that traffic nearby would be masking a lot of the very distant signals which is reflected in the Distance from receiver chart where most of the positions are <80km and almost nothing beyond 320km.
jonhawkes2030 has water to the NW so no nearby high buildings but there is some industrial complexes to the SW of the airport which may reduce the number of on ground positions available.
So all this adds up to a feeder that is working well and has results consistent with the location.
If jonhawkes2030 was reporting issues with their feeder and asking for help on the forum. Then having all this information available would save dozens of back and forth messages trying to get an idea of jonhawkes2030's situation.
