It looks like the last verified contact with them has been in 2018. Recently a youtuber went there and tried to get their attention, but couldn’t find them.
Is it possible they’re not even still around? Maybe a disease found its way onto their island and took them out. It could have even been from the last visitor in 2018.
What’s your point? We don’t have to manifest destiny every single plot of land and genocide every non-white people on the fucking planet. They can live how they want to.
