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.
i hope they’re okay too! but maybe it’s best to check up on them in a way that doesn’t bother them. they deserve to be at peace
