I have noticed that this happens often with GPSLogger users. https://gpslogger.app/
I was not able to discover which app this user is using to record and upload GPS tracks. So this situation may be different.
It may be a good issue to bring up to the greater OSM community, on the OSM talk mailing list page.
(has this note been resolved and can be closed?)
