The red flag, when used by pirates, came to mean “no quarter given”,
meaning that no mercy would be shown and no life would be spared,
while a black flag usually meant that those who surrendered without a fight would be allowed to live.
Can they be updated?
Manually or automatically, when someone travels?
Otherwise removing them flags might be good.
Might def be misleading when someone is serving on the high seas, where they are no real locations (not that this would be relevant for most).
