It looks like it was designed to be a project sticker for profiles managed by that project, which means the project should be putting it on, when they feel the need to manage a profile. That isn't a sticker to be put onto profiles, just to say they are from that area.
I would visit the project page and get information from that page and contact the leader of that group.
