I’m surprised that the effect of major rivers is big enough to be visible on a global map, at least in otherwise saline areas (Amazon, Mississippi, Congo?). Interestingly, the world’s longest river (Nile) which drains into one of the saltiest seas (Mediterranean) doesn’t register on this scale at all.

Indeed they do; thank you very much for fixing it!

The same happens also with the first two communities of the Active User Growth category:

• !business@lemmy.world, Business, 2 →828, 333 posts (331 this week)
• antennapod@lemmy.ml, Antenna Pod, 2 →828, 333 posts (331 this week)

The stats themselves also seem to be off for both: !business@lemmy.world may have gotten so many active users but certainly not 331 weekly posts (unless they got mass deleted since). !antennapod@lemmy.ml appears to only have two posts in the whole community, so both user and post numbers are probably miscalculated.

This is a very inaccurate map, as it lumps the actual Italian empire, protectorates and administrated regions all together as one. The map’s resolution is very small so it’s hard to tell, but some places are marked that were none of the above (e.g. Athens in Axis-occupued Greece).

Even worse though, this map includes regions that were never under Italian control simultaneously. Quoting from the Wikipedia image on the linked article (and which this map is an either accidental or intentional worse copy of):

Italian Colonial Empire. Every territory ever controlled by the Italian Empire as some point in time during World War II. (many of those were not under Italian control until November 1942/early 1943, and East Africa was lost before the conquest of Yugoslavia and Greece in 1941)
