SimilarWorlds, a recreation of the old site Experience Project, brings together just anyone from anywhere. I've never met such a cosmopolitan group of users with people from all walks of life, political viewpoints, and parts of the world. It can be a weird place to get into but so many users are amazing people.
SW also has amazing community and administrator policing of exploitative content. The problem exists as it does on all social media, but people really band together to stop bad actors from hurting people. I've been there for years and hope it lasts for so much longer.
