I would report it privately via private message to the facebook page admins and let them know that it's being plagiarized from another site, if your'e sure it's not nana herself posting them. maybe PM her here first to find out?
Technically, the person posting it says the info/photos come from 'website with an acquaintance who lives 2 hrs away from Delphi' - these are details/pics from her (the acquaintance's) trip there, so not claiming it is their info/pics. Just would make more sense to post a link, to me.
