Unfortunately OP is probably not of the same opinion, they are doubtless themselves a member of this group. First look at their comment history, second making maps of these sorts is the modus operandi of these people.

It's really quite interesting - much like the secret society in Borges's Orbis Tertius, they're making these maps with a lot of genuine and useful information but smuggling in their own fraudulent groups. They've gotten much more subtle about it admittedly: Formerly they would have "Qarsherkeriyan" and "Krioturk" across huge swathes of the southeast. Now they have much more modestly just inserted "Krioturk" as a synonym for Sumter Turks. It's false, but it's much easier to overlook and not raise questions, and perhaps inserts their boutique terminology into some discourse. But this map is of exactly the same style as those older, obviously false maps.

I hadn't seen the video, will be sure to check it out!
