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.
OP looks to be aware of the situation and isn’t asking whether or not to bother them. He’s asking if there is currently evidence of whether or not they are alive.
