I looked at the all-time stats for Norway today, and see that I am no longer in 1st place. User @roadroid is reported to have 760k photos in Norway.
However, when filtering to show only their photos, only a few sequences are shown, for a total of no more than a few thousand photos. Also, most photos are from 2015, and I have never seen this user high up in the top list for Norway.
Unless I am overlooking a huge selection somewhere, it seems to me there is something wrong with the stats.
