I think you need to read that site a little more.
That simple shows XIV linkshell players, most of whom do not play anymore.
It's not a list of active players at all. I know the state of many of the servers on XIV because I played it for a long while, both games need server mergers but they won't do it because it's seen as a negative at a time when they are trying to push the positive.
Site creators post on her redit.
The numbers are worthless, as worthless as working out population numbers based on FFXIAH.

What she should of done is what a JP player did long ago, scrape the database and then do it again 30 days later. Compare the 2 results and ones that have changed are active, those that are the same are inactive. She instead chose a method that was pointless, other than to give false positive information.
